We can also try "cheap way": considering only plain numbers and singularities of the first level.

I mean the solutions of differential equations which are expressible as numbers and singularities of the first level.

(Formulate this exactly.)

This "cheap way" has the advantage that we can work with functions of infinite arity.

Added later: This cheap way seems to be not useful in practice. Consider $y'=f(y)$ differential equation: Then if its solution $y=g(t)$ has a singularity at point $t=a$ then the derivative at point $a$ would be $\lim_{x\rightarrow a}\frac{g(x)-g(a)}{x-a}$ to define which we would need a singularity of the second level, because $g(a)$ is itself a singularity (of the first level).
The below is some non-systematized materials. Please help to systematize it and move to other pages where it would be more appropriate.

Consider two endo-galufuncoids $\mu$ and $\nu$. Values on $\operatorname{Ob} \mu$ will behave like arguments of functions, of $\operatorname{Ob} \nu$ like values of functions.

I call $\operatorname{SLA} ( \operatorname{Ob} \mu)$ //singularity level above// $\operatorname{Ob} \mu$ the set of sets of funcoids $\nu \circ f|_{\langle \mu \rangle^{\ast} \{ x \}}$ (or alternatively of limits $\operatorname{xlim} f|_{\langle \mu \rangle^{\ast} \{ x \}}$) where $f$ is a monovalued principal funcoid in $\mathsf{FCD} ( \operatorname{Ob} \mu ; \operatorname{Ob} \nu)$. (Maybe exclude the zero funcoid?)

Consider a galufuncoid $\omega$ defined by the formulas:

$\langle \omega \rangle f = \nu \circ f$ and $\langle \omega^{- 1} \rangle f =
f \circ \nu$ and $f \mathrel{[ \omega]} g \Leftrightarrow \exists x \in
\operatorname{Ob} \nu : g^{- 1} \circ f \sqsupseteq
\operatorname{id}^{\mathsf{FCD}}_{\langle \mu \rangle^{\ast} \{ x \}}$.

We need to prove

$\langle \omega \rangle x \sim_{\omega} g^{- 1} \Leftrightarrow \exists x \in
\operatorname{Ob} \nu : g^{- 1} \circ ( \sim_{\nu}) \circ f \sqsupseteq
\operatorname{id}_{\langle \mu \rangle^{\ast} \{ x \}}$

and ?? (TODO)

The first is equivalent to $( \sim_{\nu}) \circ f \sim_{\omega} g^{- 1}
\Leftrightarrow \exists x \in \operatorname{Ob} \nu : g^{- 1} \circ ( \sim_{\nu})
\circ f \sqsupseteq \operatorname{id}^{\mathsf{FCD}}_{\langle \mu
\rangle^{\ast} \{ x \}}$.

Really, $( \sim_{\nu}) \circ f \sim_{\omega} g^{- 1} \Leftrightarrow \exists x
\in \operatorname{Ob} \nu : g^{- 1} \circ ( \sim_{\nu}) \circ f \sqsupseteq
\operatorname{id}_{\langle \mu \rangle^{\ast} \{ x \}}$.

''Conjecture'' $f \mathrel{[ \nu / \langle \mu \rangle^{\ast} \{ x \}]} g \Leftrightarrow \nu
\circ f|_{\langle \mu \rangle^{\ast} \{ x \}} = \nu \circ g|_{\langle \mu
\rangle^{\ast} \{ x \}}$ for $f,g\in\nu_{i+1}$, $x\in\operatorname{Ob}\mu$

!Upload an icon
<<tiddler spaceIcon>>
!Describe your space
If you haven't already done so, you should provide a brief decscription of yourself and what you're using this space for. To do this, just edit the [[SiteInfo]] tiddler (keeping the title the same of course).

!Change the title
<<tiddler spaceTitle>>
!Change the theme
<<tiddler colorScheme>>
!Change the menu
If you'd like to change the menu items along the top, you can edit the [[MainMenu]] tiddler.

!Change the default tiddlers
<<tiddler setDefaultTiddlers>>
!More Advanced customisations
If you know HTML and CSS, you can edit some or all of the following tiddlers to customise your space further:
* PageTemplate
* EditTemplate
* ViewTemplate
* StyleSheet
!Summary
Here we initialise the ~MathJax environment.

The Init section of this tiddler is rendered automatically when the site is loaded.  This effect was achieved by adding the line
{{{
<div style='display:none' macro='tiddler LatexNucleus##Init'></div>
}}}
to [[PageTemplate]].  It is important to add this line before the <div id='displayArea'> tag so that mathematics which appears in a default tiddle is rendered correctly.  The goal of Init is to initialise the ~MathJax environment and then call \SaveGlobals so that this freshly initialised state can be returned to at any time by use of the command \Clean.

!Init
$
%We hook the usual macro-creating Latex commands up to Richard's javascript routines.
\def\newcommand{\MetaNewCom}
\def\renewcommand{\MetaNewCom}
\def\def{\MetaDef}

%Here we make copies of the standard Latex commands which we may displace.
\let\LaTeXepsilon\epsilon
\let\LaTeXsubset\subset
\let\LaTeXrestriction\restriction

%We transclude all of the macroset tiddlers so that the macroset macros are always available.  If you create a new macroset then you'll need to add the appropriate line here so that it is detected when the site loads.
$<<tiddler BasicMacros##Code>>$
$<<tiddler KunenMacros##Code>>$
$<<tiddler GarethMacros##Code>>$

%We also include a dummy macroset, \LocalMacros, which can be used for the main extra macros of a particular tiddler.  This can be useful, for example, if you want to comment on someones work using some of your personal macros but don't want to replace any of the local definitions.
\def\LocalMacros{}

%We preload the macrosets which are considered global.
\BasicMacros
\BasicMacroAbbreviations
\BasicMacrosSupplement

%And finally we save the current state of the ~MathJax definition tables.  This is the state we return to whenever \Clean is called.  We also call \Clean here to keep the ~MathJax environment in good condition when this tiddler is viewed.  This is put in a separate mathematics block because \SaveGlobals will throw an error on every call other than the first and this error will prevent \Clean from being called if \Clean is later on in the same block.

''Variant 1''

//Functional galufuncoid// (a candidate for singularity level above) $\nu / \Delta$ of $\nu$ through filter $\Delta$ is the endo-galufuncoid defined by the formulas:

$\operatorname{Ob} ( \nu / \Delta) = \mathsf{FCD} ( \operatorname{Base} ( \Delta) ; \operatorname{Ob} \nu)$;

$\langle \nu / \Delta \rangle f = \nu \circ f$ and $\langle ( \nu / \Delta)^{-1} \rangle f = \nu^{- 1} \circ f$;

$f \sim_{\operatorname{Ob} ( \nu / \Delta)} g \Leftrightarrow g^{- 1} \circ f
\sqsupseteq \operatorname{id}^{\mathsf{FCD}}_{\Delta}$;

''Variant 2''

It seems that the above does not define a $T_2$ space. In attempt to make it $T_2$-separable, let restrict $\operatorname{Ob} ( \nu / \Delta)$ only to funcoids $f=\nu\circ F$ where $F$ is an entirely defined monovalued funcoid.

''Obvious'' $\sim_{\operatorname{Ob} ( \nu / \Delta)}$ is a symmetric relation.

''Proposition'' This is really a galufuncoid and $f \mathrel{[ \nu / \Delta]} g
\Leftrightarrow g^{- 1} \circ \nu \circ f \sqsupseteq \operatorname{id}_{\Delta}$.

''Proof'' We need to prove
\[ \langle \nu / \Delta \rangle f \sim_{\operatorname{Ob} ( \nu / \Delta)} g
   \Leftrightarrow g^{- 1} \circ \nu \circ f \sqsupseteq \operatorname{id}_{\Delta}
   \Leftrightarrow f \sim_{\operatorname{Ob} ( \nu / \Delta)} \langle ( \nu /
   \Delta)^{- 1} \rangle g. \]
Really,

$\langle \nu / \Delta \rangle f \sim_{\operatorname{Ob} ( \nu / \Delta)} g
\Leftrightarrow \nu \circ f \sim_{\operatorname{Ob} ( \nu / \Delta)} g \Leftrightarrow
g^{- 1} \circ \nu \circ f \sqsupseteq \operatorname{id}_{\Delta}$

$f \sim_{\operatorname{Ob} ( \nu / \Delta)} \langle ( \nu / \Delta)^{- 1} \rangle g
\Leftrightarrow f \sim_{\operatorname{Ob} ( \nu / \Delta)} \nu^{- 1} \circ g
\Leftrightarrow g^{- 1} \circ \nu \circ f \sqsupseteq \operatorname{id}_{\Delta}$.

''Remark'' A way to come to the above formula
\[ \forall x \in \operatorname{atoms} \Delta : f x \mathrel{[ \nu]} g x
   \Leftrightarrow \forall x \in \operatorname{atoms} \Delta : x \mathrel{[ g^{- 1}
   \circ \nu \circ f]} x \Leftrightarrow g^{- 1} \circ \nu \circ f \sqsupseteq
   \operatorname{id}_{\Delta} . \]

Hello,

If you choose to change this GettingStarted tiddler, you may wish to add the following to your new content if you expect you space to be included:

<<<
----
Hello,
''This ~GettingStarted tiddler has been customized.''
If you want to see the original system tiddler just click the following link: GettingStarted@system-info at system-info.
<<<
%/

Welcome to your brand new [[TiddlySpace|http://docs.tiddlyspace.com/TiddlySpace]].

You're almost ready to go, there are just a couple of things left to do.

!Customise your space
Go to [[SpaceSettings]] to finish customising  your space. When you're done, come back here (just scroll up). Don't worry though, this will still be open when you've finished.

!Further Customisation

For advanced options, the [[ServerSettings]] tiddler is used to enable the following features:

#index: The value is the name of a tiddler that will be presented when loading the space.  For example, when set to {{{Hello}}} for the space hello.tiddlyspace.com, navigating to that URL will present the Hello tiddler. If there is no {{{Hello}}} you will get an error.
#editor: The name of an [[editor application|http://docs.tiddlyspace.com/Example%20Tiddler%20Editors]] to edit tiddlers with.  Applications come from [[included spaces|http://docs.tiddlyspace.com/How%20do%20I%20include%2Fexclude%20spaces%3F]]

//If you do not need or understand these features there is no need to create a ServerSettings tiddler.//

To edit these options: 

* click [[here|ServerSettings]] to open the [[ServerSettings]] tiddler
* click on the edit button (the pencil icon)
* add the options you wish to set 
* click on the save button (the tick icon).

An example [[ServerSettings]] tiddler:
{{{
index: HelloThere
editor: /edit#{tiddler}
}}}

The additional text after /edit allows a tiddler to be opened in edit mode e.g:
{{{http://hello.tiddlyspace.com/edit#MyTiddler}}}

!!See Also

* [[ServerSettings shadow tiddler|http://docs.tiddlyspace.com/ServerSettings%20shadow%20tiddler]]
* [[Choosing a non-TiddlyWiki Default Application for your Space|http://docs.tiddlyspace.com/Choosing%20a%20non-TiddlyWiki%20Default%20Application%20for%20your%20Space]]

!Finished customising?
You can [[Start writing]] some [[tiddlers|http://docs.tiddlyspace.com/Tiddler]].
If you're not done tweaking yet though, you can always [[Customise this space|SpaceSettings]] a bit more.

You can also [[access and read other tiddlers in various ways|http://docs.tiddlyspace.com/Viewing%20Tiddlers]].

!Administration
If you'd like to change your password or create another space, visit "Your Account" from the [[Universal Backstage|http://docs.tiddlyspace.com/UniversalBackstage]] (the blue dot in the upper right of the page). If you'd like to add a member or [[include a space|http://docs.tiddlyspace.com/How%20do%20I%20include%2Fexclude%20spaces%3F]] visit "This Space" from the [[Universal Backstage|http://docs.tiddlyspace.com/UniversalBackstage]].

You can have as many spaces as you like and each space can have as many members as you or your group need.

!Stuck?
If you're stuck, and would like some help, please visit the [[help|http://help.tiddlyspace.com]] space, which can point you in the right direction.
See http://www.springer.com/us/book/9780387977102 for another way to prove Cartesian closedness.

This math research wiki is to solve the open problems:
* Is category $\mathbf{Fcd}$ cartesian closed?
* Is category $\mathbf{Rld}$ cartesian closed?

> [[Definition of our categories]]
> [[Description of cartesian closed categories]]
> [[Is category Fcd cartesian closed?]]
>> [[By analogy with the proof that Dig is cartesian closed]]
>>> [[Proof for Fcd using sets]]
>> [[Reducing to the fact that Dig is cartesian closed]]
> [[Is category Rld cartesian closed?]]

It also contains a complete proof that
[[Category Dig is cartesian closed]]

Before participating in this research you need to read:
* [[Algebraic General Topology. Volume 1|http://www.mathematics21.org/algebraic-general-topology.html]]
* [[Products in dagger categories with complete ordered Mor-sets|http://www.mathematics21.org/binaries/product.pdf]]

Please put your ideas and questions regarding this research topic and announces of any changes in this wiki as comments to [[this blog post|http://portonmath.wordpress.com/2013/11/25/cartesian-closed-wiki/]].

|''Author''|[[Canada East|http://tiddlywiki.canada-east.ca/]]|
|''Version''|1.3|
|''Date''|2010-10-07|
|''CodeRepository''|[[PluginMathJax|http://tiddlywiki.canada-east.ca/#PluginMathJax]]|
|''CoreVersion''|[[2.6.1|http://www.tiddlywiki.com]]|

|''Tweaks''|~MathJax location and default HTML-CSS scale changed by Gareth Davies.  I've also added a hook to a ~MathJax extension for managing local definitions written by Richard Lupton and I've set the newcommand extension to load on start-up.|
!Description
This plugin uses [[MathJax|http://www.mathjax.org/]] to typeset ([[AMS|http://www.ams.org/publications/authors/tex/amslatex]]) [[LaTeX|http://www.latex-project.org/]]  math. It can also be configured to use additional MathJax functionality.
>"MathJax is an open source JavaScript display engine for mathematics that works in all modern browsers."
!Notes
Right click any math display for a MathJax menu. The user can select the renderer and zoom settings. It performs best in [[Webkit|http://en.wikipedia.org/wiki/List_of_web_browsers#WebKit-based_browsers]] based browsers. Larger math displays such as the additional examples tiddler below can put quite a load on IE. PluginMathJax is based on: [[Plugin: jsMath|http://bob.mcelrath.org/tiddlyjsmath.html]]
!Installation
#''Backup'' your TiddlyWiki!
#It is required that the MathJax directory is installed in '''js/MathJax/''' in the same location as the TiddlyWiki html file.<br>(Or edit the script source where commented in the plugin code below after installation to match the location of your MathJax install.)
#Install this plugin (and examples tiddler linked below if desired).

!Configuration
MathJax can be manually configured if desired by editing the code below (advanced). See the [[MathJax documentation|http://www.mathjax.org/resources/docs/?configuration.html#configuration-options-by-component]] for details.
!Revision History
*v1.3, 2010-10-07, returned to original formatters design, kept modified wikify and recommended way of loading MathJax dynamically, removed the tex2jax extension and corrected several browser compatibility issues (InnerHTML for Opera and IE9).
*v1.2, 2010-10-05, removed some redundant MathJax config entries, moved modified wikify and MathJax.Hub.Queue call.
*v1.1, 2010-10-03, autoLinkWikiWords disabled in absence of DisableWikiLinksPlugin, modifed wikify.

If transclusion is the process of including content from somewhere else, by reference, then extraclusion is the process whereby content in a document is removed to another location and a reference to it is left in its place. With tiddlers, this is a good way of breaking a large tiddler down into several smaller tiddlers while maintaining the overview.

To engage extraclusion in @edit you use some special syntax that wraps around the content you wish to move to another tiddler:

{{{
    .extraclude The Name of the New Tiddler

    the content

    .extraclude
}}}

Those {{{.extraclude}}} statements are at the beginning of the line.

You can have multiple extraclusions in an edit. When the tiddlers is saved each one will be replaced with

{{{<<tiddler [[The Name of the New Tiddler]]>>}}}

and the new tiddler will be created in the same bag as the current tiddler. If the tiddler already exists it will be overwritten.

If you are editing a Markdown syntax tiddler, then the created tiddlers will also be Markdown and the markup left behind in the original tiddler will be correct Markdown transclusion syntax

{{{{{The Name of the New Tiddler}}}}}

Currying for sets is $\langle f \rangle ( X \times Y) = \bigcup \langle \langle \sim f \rangle X
\rangle Y$ (as it's easy to prove). This simple formula gives hope, but...

It does not work with sets because an analogy for sets of the last equality of the above mentioned long formula would be:

$\forall X, Y, V, W \in \mathscr{P} \operatorname{Ob} A : \left( X \times V \mathrel{[
A \times B]^{\ast}} Y \times W \Rightarrow \langle f \rangle ( X \times V)
\mathrel{[ C]^{\ast}} \langle f \rangle ( Y \times W) \right) \Rightarrow \\ f : A
\times B \rightarrow C$

but this implication seems false.

/***
|''Name''|ImageMacroPlugin|
|''Version''|0.9.4|
|''Description''|Allows the rendering of svg images in a TiddlyWiki|
|''Author''|Osmosoft|
|''License''|[[BSD|http://www.opensource.org/licenses/bsd-license.php]]|
|''Notes''|Currently only works in modern browsers (not IE)|
|''Requires''|BinaryTiddlersPlugin|
!Usage
{{{<<image SVG>>}}} will render the text of the tiddler with title SVG as an SVG image (but not in ie where it will fail silently)
!!Parameters
width/height: specify width/height parameters
link: make the image link to a given location
tiddlyLink: link to a tiddler

!Notes
Binary tiddlers in TiddlyWeb when passed through the wikifier will be shown as images.
eg. {{{<<view text wikified>>}}} on a binary tiddler will show the image.
{{{<<view fieldname image>>}}}
will render the value of the tiddler field 'fieldname' as an image. This field can contain a tid
{{{<<image SiteIcon>>}}}
will create an image tag where the tiddler has content type beginning image and not ending +xml
will attempt to create svg object in other scenarios
{{{<<image /photos/x.jpg>>}}}
will create an image tag with src /photos/x.jpg as long as there is not a tiddler called /photos/x.jpg in 
which case it will render that tiddler as an image. Note for the case of svg files it will attempt to render as an svg if possible via the image
tag. It doesn't embed the svg in the dom for security reasons as svg code can contain javascript.

Categories $\mathbf{Dig}$, $\mathbf{Fcd}$, and $\mathbf{Rld}$ are respectively categories of:
# discretely continuous maps between digraphs;
# (proximally) continuous maps between endofuncoids;
# (uniformly) continuous maps between endoreloids.

''Definition'' //Digraph// is an endomorphism of the category $\mathbf{Rel}$.

For a digraph $A$ we denote $\operatorname{Ob} A$ the set of vertexes or $A$ and $\operatorname{GR} A$ the set of edges or $A$.

''Definition'' Category $\mathbf{Dig}$ of digraphs is the category whose objects are digraphs and morphisms are discretely continuous maps between digraphs. That is morphisms from a digraph $\mu$ to a digraph $\nu$ are functions (or more precisely morphisms of $\mathbf{Set}$) $f$ such that $f \circ \mu \sqsubseteq \nu \circ f$ (or equivalently $\mu \sqsubseteq f^{- 1} \circ \nu \circ f$ or equivalently $f \circ \mu \circ f^{- 1} \sqsubseteq \nu$).

''Remark'' Category of digraphs is sometimes defined in an other (non equivalent) way, allowing multiple edges between two given vertices.

''Definition'' Category $\mathbf{Fcd}$ of continuous maps between endofuncoids is the category whose objects are endofuncoids and morphisms are proximally continuous maps between endofuncoids. That is morphisms from an endofuncoid $\mu$ to an endofuncoid $\nu$ are functions (or more precisely morphisms of $\mathbf{Set}$) $f$ such that $\uparrow^{\mathsf{FCD}} f \circ \mu \sqsubseteq \nu \circ \uparrow^{\mathsf{FCD}} f$ (or equivalently $\mu \sqsubseteq \uparrow^{\mathsf{FCD}} f^{- 1} \circ \nu \circ \uparrow^{\mathsf{FCD}} f$ or equivalently $\uparrow^{\mathsf{FCD}} f \circ \mu \circ \uparrow^{\mathsf{FCD}} f^{- 1} \sqsubseteq \nu$).

''Definition'' Category $\mathbf{Rld}$ of continuous maps between endoreloids is the category whose objects are endoreloids and morphisms are uniformly continuous maps between endoreloids. That is morphisms from an endoreloid $\mu$ to an endoreloid $\nu$ are functions (or more precisely morphisms of $\mathbf{Set}$) $f$ such that $\uparrow^{\mathsf{RLD}} f \circ \mu \sqsubseteq \nu \circ \uparrow^{\mathsf{RLD}} f$ (or equivalently $\mu \sqsubseteq \uparrow^{\mathsf{RLD}} f^{- 1} \circ \nu \circ \uparrow^{\mathsf{RLD}} f$ or equivalently $\uparrow^{\mathsf{RLD}} f \circ \mu \circ \uparrow^{\mathsf{RLD}} f^{- 1} \sqsubseteq \nu$).

Unless you're delighted with the default theme you can make some quick changes by generating a new random color palette, hit this button to cycle through some alternatives.

<<RandomColorPaletteButton saturation_pale:0.67 saturation_light:0.53
saturation_mid:0.43 saturation_dark:0.06 pale:0.99 light:0.85 mid:0.5 dark:0.31>>

You can also change the look and feel completely by installing a new theme. To do this, find one you like in the @themes space, note down the name, and include it in this space by going to the space menu. You can reach the space menu by clicking on the blue and pink circle at the top-right of the page and chooshing "THIS SPACE". Here are a few to check out:
* @pip
* @caspian-ii
* @basalt
* @simplicity
* @cheesecake
* @jelly-doughnut

(//Note that if you are using a custom TiddlySpace install, these themes may not be present.//)

{{SiteInfo}}
There are a lot of interesting people using ~TiddlySpace that you might like to keep track of and interact with. There are a number of ways of doing this.

If you see a number in the speech bubble in one of your tiddlers, it means that someone is writing about the same thing as you. You can find out what they're saying by clicking on it. Likewise, if you see something interesting in someone else's space, you can respond to it and write up your own thoughts on the subject by clicking "Reply to this tiddler".

Additionally, if you find anyone interesting, or you find an interesting looking space and you'd like to know when it's changed, you can "follow" that space. To do this, simply create a tiddler with the title: {{{@space-name}}} and tag it {{{follow}}}. If you want, you can store some notes about that space in the body of the tiddler.

If you then want to know what happening, simply [[include|How do I include/exclude spaces?]]@docs the @tivity space and then visit your activity stream at [[/activity|/activity]], or just visit the @tapas space directly.

!Not sure who to follow?
Here's a few suggestions:
* @fnd
* @cdent
* @pmario
* @bengillies
* @dickon

!Usage
Tag a tiddler with "follow" to express a list of followers.
Using the {{{<<followTiddlers X>>}}}
will reveal the number of tiddlers with name X in the set of spaces the *current* user viewing your space follows.
{{{<<following jon>>}}} will list all the users following Jon.
{{{<<followers jon>>}}} will list all the followers of jon.
{{{<linkedTiddlers>>}}} will list all tiddlers across TiddlySpace linked to the current tiddler
{{{<linkedTiddlers follow:yes>>}}} will list all tiddlers across TiddlySpace that come from your list of followers
adds spaceLink view type {{{<<view server.bag spaceLink>>}}} creates a link to the space described in server.bag
{{{<<view server.bag spaceLink title>>}}} makes a link to the tiddler with title expressed in the field title in space server.bag
If no name is given eg. {{{<<following>>}}} or {{{<<follow>>}}} it will default the current user.

<<tiddler SiteInfo>>

To try it there are two steps, the first required, the second and third optional: 

* Include the edit space in your space. 
* Add the following lines to or create a tiddler called 'HtmlJavascript' (If jquery is already in there, there's no need to have it twice.)
{{{
   /bags/edit_public/tiddlers/editedit.js 
}}}
* If you want to to use edit as the default editor for missing tiddlers, edit the ServerSettings tiddler and add:
{{{
    editor: /edit#{tiddler}
}}}

Then when you visit {{{/edit}}} in your own space, you'll find an editor.

* You can select a tiddler to edit from the sidebar by clicking on the pen icon.
* Clicking a tiddler title will take you to view that tiddler.
* Clicking on a tag in the lower left will add that tag to the tiddler. Click again to remove the tag.
* In the upper right you save, revert or delete.
* Below that are options for choosing the type of the tiddler. You can create other things besides tiddlywiki text: Markdown and raw HTML, CSS or ~JavaScript.
* Edit supports client-side [[extraclusion]].

You can start edit from a link and by providing some information in the hash of the URI you can tell it about the new tiddler you want to create:

{{{
    /edit#<title>/<tags>/<type>
}}}

* tags are formatted as they are in TiddlyWiki (double square brackets around tags containing spaces)
* type is a content-type, such as {{{text/x-markdown}}}

If [[using plain funcoids|Using plain funcoids]] does not work in some reason, we may attempt to replace funcoids with some generalization of funcoids, such as pointfree funcoids, or more generaly [[galufuncoids|Galufuncoids]].

This approach would also require to redefine [[generalized limit]], because as it is now defined it is always a set of funcoids.

This way if we succeed is the best way to create metasingular numbers because, it (if we succeed) involves just funcoids not some fancy generalization of funcoids.

Approximate definition of "singularity level": //Singularity level// is a transitive, $T_2$-separable endofuncoid.

Now define the funcoid $\nu_{i+1}=\operatorname{SLA}(\nu_i)$:

$\operatorname{Ob}(\nu_{i+1})$ is defined as the set of all generalized limits (having fixed $\mu$, $\nu$, and $G$).

$X \mathrel{[ \nu_{i+1}]^{\ast}} Y \Leftrightarrow \exists z \in \bigcup \operatorname{Ob} \nu \forall K \in \operatorname{up} z \exists x \in \bigcup X, y \in \bigcup Y : x, y\sqsubseteq K$.

The trouble is to prove that the funcoid $\nu_{i+1}$ exists (is really a funcoid).

$\neg(X \mathrel{[ \nu_{i+1}]^{\ast}} \emptyset)$ and $\neg(\emptyset \mathrel{[ \nu_{i+1}]^{\ast}} Y)$ are obvious. We need to prove
$$I\cup J \mathrel{[ \nu_{i+1}]^{\ast}} Y \Leftrightarrow I \mathrel{[ \nu_{i+1}]^{\ast}} Y \vee J \mathrel{[ \nu_{i+1}]^{\ast}} Y$$ and
$$X \mathrel{[ \nu_{i+1}]^{\ast}} I\cup J \Leftrightarrow X \mathrel{[ \nu_{i+1}]^{\ast}} I \vee X \mathrel{[ \nu_{i+1}]^{\ast}} J.$$

Let's attempt to prove the first of the above equations (the second is dual).

$I \cup J \mathrel{[ \operatorname{SLA} ( \nu)]^{\ast}} Y \Leftrightarrow \\ \exists z
\in \bigcup \operatorname{Ob} \nu \forall K \in \operatorname{up} z \exists x \in \bigcup I \cup \bigcup J, y \in \bigcup Y :
x, y \sqsubseteq K \Leftrightarrow \\

\exists z \in \bigcup \operatorname{Ob} \nu \forall K \in \operatorname{up} z : ( \exists x \in \bigcup I \cup
\bigcup J : x \sqsubseteq K \wedge \exists y \in \bigcup Y : y \sqsubseteq K) \Leftrightarrow \\

\exists z \in \bigcup \operatorname{Ob} \nu \forall K \in \operatorname{up} z \exists x \in \bigcup I \cup \bigcup J :
x \sqsubseteq K \wedge \\ \exists z \in \bigcup \operatorname{Ob} \nu \forall K \in \operatorname{up} z
\exists y \in \bigcup Y : y \sqsubseteq K \Leftrightarrow \\

?? \\

\exists z \in \bigcup \operatorname{Ob} \nu : ( \forall K \in \operatorname{up} z \exists x \in \bigcup I : x
\sqsubseteq K \vee \\ \forall K \in \operatorname{up} z \exists x \in \bigcup J : x \sqsubseteq
K) \wedge \exists z \in \bigcup \operatorname{Ob} \nu \forall K \in \operatorname{up} z \exists y \in
\bigcup Y : y \sqsubseteq K \Leftrightarrow \\

( \exists z \in \bigcup \operatorname{Ob} \nu \forall K \in \operatorname{up} z \exists x \in \bigcup I : x
\sqsubseteq K \vee \\ \exists z \in \bigcup \operatorname{Ob} \nu \forall K \in \operatorname{up} z
\exists x \in \bigcup J : x \sqsubseteq K) \wedge \exists z \in \bigcup \operatorname{Ob} \nu \forall
K \in \operatorname{up} z \exists y \in \bigcup Y : y \sqsubseteq K \Leftrightarrow \\

( \exists z \in \bigcup \operatorname{Ob} \nu \forall K \in \operatorname{up} z \exists x \in \bigcup I : x
\sqsubseteq K \wedge \exists z \in \bigcup \operatorname{Ob} \nu \forall K \in \operatorname{up} z
\exists y \in \bigcup Y : y \sqsubseteq K) \vee \\ ( \exists z \in \bigcup \operatorname{Ob} \nu \forall
K \in \operatorname{up} z \exists x \in \bigcup J : x \sqsubseteq K \wedge \exists z \in
\bigcup \operatorname{Ob} \nu \forall K \in \operatorname{up} z \exists y \in \bigcup Y : y \sqsubseteq K)
\Leftrightarrow \\

( \exists z \in \bigcup \operatorname{Ob} \nu : ( \forall K \in \operatorname{up} z \exists x \in \bigcup I :
x \sqsubseteq K \wedge \forall K \in \operatorname{up} z \exists y \in \bigcup Y : y
\sqsubseteq K)) \vee \\ ( \exists z \in \bigcup \operatorname{Ob} \nu : ( \forall K \in \operatorname{up}
z \exists x \in \bigcup J : x \sqsubseteq K \wedge \forall K \in \operatorname{up} z \exists y
\in \bigcup Y : y \sqsubseteq K)) \Leftrightarrow \\

( \exists z \in \bigcup \operatorname{Ob} \nu : ( \forall K \in \operatorname{up} z : ( \exists x \in
\bigcup I : x \sqsubseteq K \wedge \exists y \in \bigcup Y : y \sqsubseteq K))) \vee \\ \exists z
\in \bigcup \operatorname{Ob} \nu \forall K \in \operatorname{up} z : ( \exists x \in \bigcup J : x
\sqsubseteq K \wedge \exists y \in \bigcup Y : y \sqsubseteq K) \Leftrightarrow \\

I \mathrel{[ \operatorname{SLA} ( \nu)]^{\ast}} Y \vee J \mathrel{[ \operatorname{SLA} (
\nu)]^{\ast}} Y$.

To finish the proof we need to fulfill ?? in the above formula. For this it's enough to prove

$\forall K \in \operatorname{up} z \exists x \in \bigcup I\cup \bigcup J : x \sqsubseteq K \Rightarrow \\ \forall K \in \operatorname{up}
z \exists x \in \bigcup I : x \sqsubseteq K \vee \forall K \in \operatorname{up} z \exists x
\in \bigcup J : x \sqsubseteq K$.

If $z=\uparrow Z$ is a principal funcoid, then

$\forall K \in \operatorname{up} z \exists x \in \bigcup I\cup \bigcup J : x \sqsubseteq K \Rightarrow \\ 
\exists x \in \bigcup I\cup \bigcup J : x \sqsubseteq z \Rightarrow \\
\exists x \in \bigcup I : x \sqsubseteq z \vee \exists x \in \bigcup J : x \sqsubseteq z \Rightarrow \\
\forall K \in \operatorname{up}
z \exists x \in \bigcup I : x \sqsubseteq K \vee \forall K \in \operatorname{up} z \exists x
\in \bigcup J : x \sqsubseteq K$.

Following the idea of [[the proof in this math.stackexchange.com question|http://math.stackexchange.com/questions/562908/an-implication-involving-filters#562974]] it is easy to show that our implication is true if $\operatorname{up} z$ is closed regarding finite meets. See [[this page|Singularities funcoids: some special cases]] for attempts to set it true.
The question is whether our statement holds for non-principal funcoids. Or is there a counterexampe?
@import url(http://straightwsgi.tiddlyspace.com/bags/straightwsgi_public/tiddlers/HtmlCss);
We are not only to prove (or maybe disprove) that our categories are cartesian closed, but also to find (if any) explicit formulas for exponential transpose and evaluation.

''Definition'' A category is //cartesian closed// iff:
# It has finite products.
# For each objects $A$, $B$ is given an object $\operatorname{MOR} ( A ; B)$ (//exponentiation//) and a morphism $\varepsilon^{\mathbf{Dig}}_{A, B} : \operatorname{MOR} ( A ; B) \times A \rightarrow B$.
# For each morphism $f : Z \times A \rightarrow B$ there is given a morphism (//exponential transpose//) $\sim f : Z \rightarrow \operatorname{MOR} ( A ; B)$.
# $\varepsilon_{B,C} \circ ( \sim f \times 1_A) = f$ for $f : A \rightarrow B \times C$.
# $\sim ( \varepsilon_{B,C} \circ ( g \times 1_A)) = g$ for $g : A \rightarrow \operatorname{MOR} ( B ; C)$.

We will also denote $f\mapsto (-f)$ the reverse of the bijection $f\mapsto (\sim f)$.

Our purpose is to prove (or disprove) that categories $\mathbf{Dig}$, $\mathbf{Fcd}$, and $\mathbf{Rld}$ are cartesian closed. Note that they have finite (and even infinite) products is already proved in http://www.mathematics21.org/binaries/product.pdf

Alternative way to prove:
you can prove that the functor $-\times B$ is left adjoint to the exponentiation $-^B$ where the counit is given by the evaluation map.
We attempt to prove that $\operatorname{GR} z$ is closed regarding finite intersections.

For consideration of this, let's consider two special cases (first of which is a specialization of the second).

Let $\mu=\nu$ be the natural proximity on real numbers $\mathbb{R}$.

Let $\Delta$ is the entourage filter of zero.

1. $z=\Delta\times^{\mathsf{FCD}}\Delta$.

2. $z=\nu\circ (\uparrow^{\mathsf{FCD}} f)|_{\Delta}$ for an arbitrary function $f:\mathbb{R}\rightarrow\mathbb{R}$.

(1) is [[also formulated in elementary terms|http://math.stackexchange.com/questions/568513/is-a-set-closed-under-finite-intersections-about-filters]] (without using funcoids).

These two above conjectures are shown to be false by a counter-example in [[this blog post|http://portonmath.wordpress.com/2013/12/18/a-negative-result-on-a-conjecture/]]. It is a discouraging result as it seems from it the plain funcoids can't be used for the multilevel theory of singularities.

We can attempt to set exponential, transposition, and evaluation in either of two ways (it is conjectured that these two ways are equivalent).

;The first way
:See below
;The second way
:See [[Reducing to the fact that Dig is cartesian closed]]
;The third way
:Reduce to [[cartesian closedness of Rld|Is category Rld cartesian closed?]] (however proving that $\mathbf{Rld}$ is cartesian closed is probably harder to prove than that $\mathbf{Fcd}$ is cartesian closed).

!!The first way
* Exponential object $\operatorname{MOR(A;B)}$ is:
** Object $\operatorname{Ob}\operatorname{MOR(A;B)} = (\operatorname{Ob} B)^{\operatorname{Ob} B}$;
** Graph is $\operatorname{GR} \operatorname{MOR} ( A ; B) = \uparrow^{\mathsf{FCD}} \left\{ ( f ; g) \,|\, f, g \in \operatorname{Mor}_{\mathbf{Set}} (\operatorname{Ob} A;\operatorname{Ob} B) \wedge \uparrow^{\mathsf{FCD}}g \circ A \circ \uparrow^{\mathsf{FCD}}f^{- 1} \sqsubseteq B \right\}$.
* Transposition is uncurrying.
* Evaluation is $\varepsilon_{A, B} x = \langle \operatorname{Pr}^{(A)}_0 x \rangle \operatorname{Pr}^{(A)}_1 x$.

There are basically two ways to prove that $\mathbf{Fcd}$ is cartesian closed:

> [[By analogy with the proof that Dig is cartesian closed]]
> [[Reducing to the fact that Dig is cartesian closed]]
It is probably a simpler way to prove that $\mathbf{Fcd}$ is cartesian closed by embedding it into $\mathbf{Dig}$ (which is [[already known to be cartesian closed|Category Dig is cartesian closed]]).

$\mathbf{Fcd}$ can be embedded into $\mathbf{Dig}$ by the formulas:
* $A \mapsto \langle A \rangle$;
* $f \mapsto \langle f \rangle$.

That this really maps a morphism of $\mathbf{Fcd}$ into a morphism of $\mathbf{Dig}$ follows from the fact that $\langle g\circ f\rangle = \langle g\rangle\circ\langle f\rangle$.

Obviously this embedding (denote it $T$) is an injective (both on objects and morphisms) functor.

We will define:
* $\varepsilon^{\mathbf{Fcd}}_{A, B} = T^{-1} \varepsilon^{\mathbf{Dig}}_{T A, T B}$;
* $\sim^{\mathbf{Fcd}} f = T^{-1} \sim^{\mathbf{Dig}} T f$.

Due to functoriality and injectivity of $T$ it is enough to prove that above defined $\varepsilon^{\mathbf{Fcd}}_{A, B}$ and $\sim^{\mathbf{Fcd}} f$ exist and are morphisms of $\mathbf{Fcd}$.

$\varepsilon^{\mathbf{Dig}}_{T A, T B} \ne T\varepsilon^{\mathbf{Fcd}}_{A, B}$ because $\varepsilon^{\mathbf{Dig}}_{T A, T B}$ accepts ordered pairs as the argument and $T \varepsilon^{\mathbf{Fcd}}_{A, B}$ accepts sets as the argument. So this is a dead end. Can the proof idea be salvaged?

This issue was raised in [[this blog post|http://portonmath.wordpress.com/2013/11/12/singularities-wiki/]]. You may comment on this blog post about your research and questions on the issues raised on this wiki.

Motto: ''Unravel the mystery of singularities.''

Warning: It is a rough draft and may contain errors.

In my book [[Algebraic General Topology. Volume 1|http://www.mathematics21.org/algebraic-general-topology.html]] I introduced the concept of [[generalized limit]]. (Generalized limit, unlike traditional limit, is defined for arbitrary values, even in singularity points.)

This wiki is intended to rigorously define (and research) singularities using values of generalized limits in equations. The trouble is that generalized limit is not a number (technically it is a set of funcoids) and can't be put into the same equation as a number without "type casting". It is possible to cast values (such as real numbers) into sets of funcoids to move them into the same "space" as generalized limits. But this does not work because there may be singularities "of level above" that is "singularities of singularities".

Thus there should be produced an infinite hierarchy of singularities: starting from numbers (such as real numbers), then plain singularities, then singularities of singularities, etc.

In [[this rough draft article|http://www.mathematics21.org/binaries/reduced-limit.pdf]] I attempted to introduce "metasingular numbers" to construct an infinite hierarchy of singularities and overcome this problem. The problem appeared to be difficult however.

So this wiki is to define metasingular numbers exactly and construct the infinite hierarchy of singularities.

Replacing limit in the definition of derivative with the above defined reduced limit, the base set $\operatorname{Ob} \mu$ with MSN and operations $f$ on the set $\operatorname{Ob} \mu$ with corresponding operations on MSN, we get a new interpretation of a differential equation (DE) (ordinary or partial).

Let call such (enhanced) differential equations //meta-singular equations// (as opposed to //non-singular equations// that is customary differential equations).

There arise the following questions:

''Definition'' I call a solution of a DE a //trivial restriction// if it is a restriction (to the set of non-singular points) of exactly one enhanced DE.

We need to find when there are solutions which are not trivial restrictions.

Then we can split such non-trivial solutions into following classes:
* "added solutions" are solutions whose restriction to non-singularity points is not a non-singular solution;
* "alternate solutions" is when an non-singular solution is a restriction of more than one meta-singular solution;
* "disappearing solutions" when a non-singular solution is not a restriction of a meta-singular solution.

The most obvious way for proof attempt that $\mathbf{Fcd}$ is cartesian closed is an analogy with [[the proof that Dig is cartesian closed|Category Dig is cartesian closed]].

Use the exponential object, transposition, and evaluation as defined in [[this page|Is category Fcd cartesian closed?]]

Consider the long formula at the bottom of [[this page|Category Dig is cartesian closed]]. The proof would arise if we replace $x$ and $y$ in this formula with filters and operations and relations on set element with operations and relations on filters.

This proof could be simplified in either of two ways:
* replace $x$ and $y$ with ultrafilters, see [[Proof for Fcd using ultrafilters]];
* replace $x$ and $y$ with sets (principal filter), see [[Proof for Fcd using sets]].

This is not quite easy however, because we need to calculate uncurrying for a entirely defined monovalued principal funcoid (what is essentially the same as a function of a $\mathbf{Set}$-morphisms) taking either ultrafilters or principal filters as arguments. Such (generalized) uncurrying is not quite easy.

To sum what we need to prove:
* Transposition is a morphism.
* Evaluation is a morphism.

To prove that $\operatorname{GR} ( \Delta \times^{\mathsf{FCD}} \Delta)$ is closed under finite intersections, it's enough to prove that for every $f \in \operatorname{GR} ( \Delta \times^{\mathsf{FCD}} \Delta)$ there is a positive $\varepsilon$ such that $\forall x \in ( - \varepsilon ; \varepsilon) : f x \in \Delta$.

Really, under this assumption:

For $g \in \operatorname{GR} ( \Delta \times^{\mathsf{FCD}} \Delta)$ exists $\zeta > 0$ such that $\forall x \in ( - \zeta ; \zeta) : g x \in \Delta$. Let $\eta = \min \{ \varepsilon, \zeta \}$. So $\forall x \in ( - \eta ; \eta) : ( \langle f \rangle x \in \Delta \wedge \langle g \rangle x \in \Delta)$ and so $\forall x \in ( - \eta ; \eta) : \langle f \cap g \rangle x \in \Delta$ that is $\forall x \in ( - \eta ; \eta) : \langle \uparrow^{\mathsf{FCD}} ( f \cap g) \rangle^{\ast} \{ x \} \sqsupseteq \Delta$ and consequently $f \cap g \in \operatorname{GR} ( \Delta \times^{\mathsf{FCD}} \Delta)$.

!!Documentation
This plugin provides wikitext formatters for referencing another [[space|Space]] on the same TiddlySpace server, as in the following examples:
<<<
  {{{@space}}} -- @space 
  {{{~@space}}} -- ~@space 
  {{{Tiddler@space}}} -- Tiddler@space
  {{{[[Tiddler Title]]@space}}} -- [[Tiddler Title]]@space 
  {{{[[Link text|Tiddler Title]]@space}}} -- [[Link text|Tiddler Title]]@space
<<<
Links to tiddlers with a title begining with an "@" remain as tiddlyLinks:
<<<
  {{{[[@tiddler]]}}} -- [[@tiddler]]
<<<
and these may be changed into a space link using {{{@@}}}:
<<<
  {{{[[@@space]]}}} -- [[@@space]]
  {{{[[Link to an another space|@@space]]}}} -- [[Link to another space|@@space]]
  {{{[[@space|@@space]]}}} -- [[@space|@@space]]
<<<
TiddlySpace includes the [[TiddlySpaceLinkPlugin]] which provides WikiText markup for linking to other spaces on the same server. For example @glossary is a link to the {{{glossary}}} space and [[Small Trusted Group]]@glossary a link to an individual tiddler in the @glossary space. Prefixing the link with a tilde escapes the link, for example {{{~@space}}}.
Email addresses, for example joe.bloggs@example.com and mary@had.a.little.lamb.org should be unaffected.
!!Features
The plugin provides external links decorated so that other plugins may be included to add features such as the ability to dynamically pull externally linked tiddlers into the current TiddlyWiki.
Wikitext linking to a space on another server, for example from a tiddler in a space on tiddlyspace.com to a tiddler or a space on example.com, isn't currently supported.

We start with some "space" $\nu$ (on a set $\operatorname{Ob}\nu$) (for example it may be set $\mathbb{R}$ of real numbers or an Euclidean space). The zeroth singularity level $\nu_0=\nu$.

Then we need to define "singularity level above" (SLA for short) and assign $\nu_{i+1}=SLA(\nu_i)$ (also on the set $\operatorname{Ob}\nu$). Thus we get an infinite chain of singularity levels.

$\nu_{i+1}$ should include [[generalized limit]] of functions with values in $\nu_i$. So limits on $\nu_i$ are (generally) singularities of $\nu_{i+1}$.

Also we define function (it should be an injection) $\tau:\nu_i\rightarrow\nu_{i+1}$ (raising singularity level). I denote its partial inverse (existing because it is an injection) as $r$. Given a point $x$ of $\nu_k$, we apply $r$ to it as many times as possible: $y=r(r(r\dots r(x)))$. $y$ may be of the same singularity level as $x$ or any lower singularity including possibly the non-singular value (of $\operatorname{Ob}\nu_0$).

I call the set of all values $y$ obtained as explained in the previous paragraph "metasingular numbers" (MSN).

Note that the function $\tau$ defined in [[my book|http://www.mathematics21.org/algebraic-general-topology.html]] is injection when the spaces in consideration are $T_2$. So we probably need to require $T_2$-separability throughout this research.

Throughout this research we will fix (in the argument space $\mu$) a filter $\Delta$ (on which the limits are taken). One way to obtain $\Delta$ is to fix some "space" $\mu$ (the space of arguments as opposed to $\nu$, space of values) and define $\Delta=\langle\mu\rangle^{\ast}\{x\}$ for some argument point $x$.

Algebraic General Topology and related stuff
We may attempt to prove that $\mathbf{Rld}$ is cartesian closed by embedding it into supposedly cartesian closed category $\mathbf{Fcd}$ by the function $\rho$:

$\langle \rho f \rangle x = f \circ x \quad \text{and} \quad \langle \rho f^{- 1} \rangle y = f^{- 1} \circ y$.

!Usage
The viewRevisions macro can be attached to any element, which should be passed
in as a parameter.

For example:

&lt;&lt;viewRevisions page:10 link:"<<view modified date>>"&gt;&gt;

would show the revisions "stack of cards" view, 10 at a time, when the modified
date is clicked.

[[I|Victor Porton]] am not a expert in general relativity (I am not even a professional mathematician).

But it looks like that the equations of general relativity can be converted (as described above) into meta-singular equations. For the special case of general relativity equations, the above classes are:
* "added solutions" would possibly characterize a "world above" described not with real numbers as our world but with singularities. This may or may not be of physical interest.
* "alternate solutions" would characterize black (or white) holes with additional information hidden inside. This additional information may probably solve the well known paradox of information disappearing when it falls into a black hole.
* "disappearing solutions" would mean that the laws of nature are possibly more restrictive than considered in more traditional physics. Could it resolve time-machine related paradoxes?

I again repeat that I am not an expert in general relativity. I seek collaboration with general relativity experts to solve the problems I've formulated.

I think (except of the case of the negative result that is there are no non-trivial solutions) this research is destined to receive Nobel Prize and/or Fundamental Physics Prize. I want my half.

Note that the group $G$ (see the definition of generalized limit in my book) for general relativity can be defined in two different ways: as the group of homeomorpisms of the curved space or as the group of only uniformly continuous (in both directions) bijections. This gives us ''two'' new theories of general relativity.
Victor Porton's math problems
Let $f$ is an $n$-ary ($n$ is an arbitrary possibly infinite index set) function on $\operatorname{Ob} \nu$. Then define function $f'$ on $\operatorname{SLA} (
\operatorname{Ob} \nu)$ as: \[ f' ( b) = \left\{ g \circ \prod^{( A)} b \hspace{1em} | \hspace{1em} g \in f' \right\} . \]

The above induces a trivial definition of functions on MSN but only for functions of finite arity (because having a finite set of MSN we can raise them to the same (maximum) level).

SVG icons are drawn from tiddlers titled {{{<command>.svg}}}
In readonly mode a tiddler called {{{<command>ReadOnly.svg}}} will be used if it exists.
!TODO
* rename (IconToolbarPlugin?)

Click the "new tiddler" button towards the top right of the screen to write something in your space. You'll need to give it a title, some content and, optionally, some tags that will help you identify it later.

!Stuck for ideas?
Not sure what to write about? Not sure what to keep in your space? Other people use ~TiddlySpace for almost anything. How about some of the following:

* [[Save interesting sites|http://bookmarks.tiddlyspace.com]], images or articles from around the web so that you can refer back to them.
* [[Record your family tree|http://familytree.tiddlyspace.com]], store notes on long lost relatives or ancestors and map their relationship to you.
* [[Make up a pocketbook|http://pocketbook.tiddlyspace.com]] to store some useful information in, then print it out, [[fold it up|http://www.pocketmod.com/]], and take it with you.
* [[Plan your holiday|http://the-web-is-your-oyster.tiddlyspace.com/]], record where you're planning to go, note down places of interest and refer back to it later.
* [[Create a mindmap|http://mindmaps.tiddlyspace.com/]] to visualise your inner thoughts and see how they relate to each other.
* [[Set up a questionnaire|http://questionnaire.tiddlyspace.com/]] and get all your friends to answer it.

If you don't like any of those ideas, you can still use this space directly to keep notes and link them together, make a todo list and keep track of everything you're doing, or any one of a hundred million other things.

Still stuck? Check out the @featured space for more suggestions.

|''Requires''|TiddlySpaceConfig|
|''Source''|http://github.com/TiddlySpace/tiddlyspace/raw/master/src/plugins/ToggleTiddlerPrivacyPlugin.js|
!Notes
When used in conjunction with TiddlySpaceTiddlerIconsPlugin changing the privacy setting will also interact with any privacy icons.

Currently use of
{{{<<setPrivacy defaultValue:public>>}}} is in conflict with {{{<<newTiddler fields:"server.workspace:x_private">>}}}

There is an option, found in the tweak tab of the backstage, called txtPrivacyMode. Set this to either ''public'' or ''private'' depending on your security preference. If you choose not to set it then it will default to ''public''.
!Params
defaultValue:[private|public]
Allows you to set the default privacy value (Default is private)

We try to define the function $\operatorname{SLA}:\nu_i\rightarrow\nu_{i+1}$ (raising singularity level) in some different ways.

In every way if possible we should put some restriction what $\nu_i$ is. For example we may require that it is a funcoid, or maybe some more general thing.

We may put additional restrictions such as $\nu_i$ to be $T_2$-separable or a transitive funcoid or whatever.
Category of digraphs is the simplest of our three categories and it is easy to demonstrate that it is cartesian closed. I demonstrate cartesian closedness of $\mathbf{Dig}$ mainly with the purpose to show a pattern similarly to which we may probably demonstrate our two other categories are cartesian closed.

Let $G$ and $H$ be graphs:
* $\operatorname{Ob} \operatorname{MOR} ( G ; H) = ( \operatorname{Ob} H)^{\operatorname{Ob} G}$;
* $( f ; g) \in \operatorname{GR} \operatorname{MOR} ( G ; H) \Leftrightarrow \forall ( v ; w) \in \operatorname{GR} G : ( f ( v) ; g ( w)) \in \operatorname{GR} H$ for every $f, g \in \operatorname{Ob} \operatorname{MOR} ( G ; H) = ( \operatorname{Ob} H)^{\operatorname{Ob} G}$;

$\operatorname{GR} 1_{\operatorname{MOR} ( B ; C)} = \operatorname{id}_{\operatorname{Ob} \operatorname{MOR} ( B ; C)} = \operatorname{id}_{( \operatorname{Ob} H)^{\operatorname{Ob} G}}$

Equivalently

$( f ; g) \in \operatorname{GR} \operatorname{MOR} ( G ; H) \Leftrightarrow \forall ( v ; w) \in \operatorname{GR} G : g \circ \{ ( v ; w) \} \circ f^{- 1} \subseteq \operatorname{GR} H$

$( f ; g) \in \operatorname{GR} \operatorname{MOR} ( G ; H) \Leftrightarrow g \circ ( \operatorname{GR} G) \circ f^{- 1} \subseteq \operatorname{GR} H$

$( f ; g) \in \operatorname{GR} \operatorname{MOR} ( G ; H) \Leftrightarrow \langle f \times^{( C)} g \rangle \operatorname{GR} G \subseteq \operatorname{GR} H$

The transposition (the isomorphism) is uncurrying.

$\sim f = \lambda a \in Z \lambda y \in A : f ( a ; y)$ that is $( \sim f) ( a) ( y) = f ( a ; y)$.

$( - f) ( a ; y) = f ( a) ( y)$

If $f : A \times B \rightarrow C$ then $\sim f : A \rightarrow \operatorname{MOR} ( B ; C)$

''Proposition'' Transposition and its inverse are morphisms of $\mathbf{Dig}$.

''Proof'' It follows from the equivalence $\sim f : A \rightarrow \operatorname{MOR} ( B ; C) \Leftrightarrow \forall x, y : ( x A y \Rightarrow ( \sim f) x ( \operatorname{MOR} ( B ; C))  ( \sim f) y) \Leftrightarrow \\ \forall x, y : ( x A y \Rightarrow \forall ( v ; w) \in B : ( ( \sim f) x v ; ( \sim f) y w) \in C) \Leftrightarrow \\ \forall x, y, v, w : ( x A y \wedge v B w \Rightarrow ( ( \sim f) x v ; ( \sim f) y w) \in C) \Leftrightarrow \\ \forall x, y, v, w : ( ( x ; v)  ( A \times B)  ( y ; w) \Rightarrow ( f ( x ; v) ; f ( y ; w)) \in C) \Leftrightarrow f : A \times B \rightarrow C$.

Evaluation $\varepsilon : \operatorname{MOR} ( G ; H) \times G \rightarrow H$ is defined by the formula:

Then evaluation is $\varepsilon_{B, C} = - ( 1_{\operatorname{MOR} ( B ; C)})$.

So $\varepsilon_{B, C} ( p ; q) = ( - ( 1_{\operatorname{MOR} ( B ; C)})) ( p ; q) = ( 1_{\operatorname{MOR} ( B ; C)}) ( p) ( q) = p ( q)$.

''Proposition'' Evaluation is a morphism of $\mathbf{Dig}$.

''Proof'' Because $\varepsilon_{B, C} ( p ; q) = - ( 1_{\operatorname{MOR} ( B ; C)})$.

It remains to prove:
* $\varepsilon_{B, C} \circ ( \sim f \times 1_{A}) = f$ for $f : A \rightarrow B \times C$;
* $\sim ( \varepsilon_{B, C} \circ ( g \times 1_{A})) = g$ for $g : A \rightarrow \operatorname{MOR} ( B ; C)$.

''Proof'' $\varepsilon_{B, C} ( \sim f \times 1_{A}) ( a ; p) = \varepsilon_{B, C} ( ( \sim f) a ; p) = ( \sim f) a p = f ( a ; p)$. So $\varepsilon_{B, C} \circ ( \sim f \times 1_{A}) = f$.

  $\sim ( \varepsilon_{B, C} \circ ( g \times 1_{A})) ( p) ( q) = ( \varepsilon_{B, C} \circ ( g \times 1_{A})) ( p ; q) = \varepsilon_{B, C} ( g \times 1_{A}) ( p ; q) = \varepsilon_{B, C} ( g p ; q) = g ( p) ( q)$. So $\sim ( \varepsilon_{B, C} \circ ( g \times 1_{A})) = g$.
If we fail to define singularities levels above to be funcoids, we need to generalize and use pointfree funcoids instead of funcoids, or even more generally below defined galufuncoids.

Let $\mathfrak{A}$ and $\mathfrak{B}$ are $\mathbf{Rel}$-morphisms. I will denote like $( \sim_{\mathfrak{A}}) = \operatorname{GR} \mathfrak{A}$ and $(\sim_{\mathfrak{B}}) = \operatorname{GR} \mathfrak{B}$.

''Definition'' //Galufuncoids// between $\mathfrak{A}$ and $\mathfrak{B}$ is a quadruple $( \mathfrak{A}; \mathfrak{B}; \alpha ; \beta)$ such that \[ \forall x \in \operatorname{Ob} \mathfrak{A}, y \in \operatorname{Ob} \mathfrak{B}: ( \alpha x \sim_{\mathfrak{B}} y \Leftrightarrow x \sim_{\mathfrak{A}} \beta y) . \]

''Definition'' $x \mathrel{[ f]} y \Leftrightarrow x \sim_{\operatorname{Src} f} \beta y$.

''Obvious'' $x \mathrel{[ f]} y \Leftrightarrow x \sim_{\operatorname{Src} f} \beta y \Leftrightarrow \alpha x \sim_{\operatorname{Dst} f} y$.

Galufuncoids are a generalization of both (pointfree) funcoids and Galois connections.

''Definition'' The //reverse// galufuncoid is defined by the formula: \[ ( \mathfrak{A}; \mathfrak{B}; \alpha ; \beta)^{- 1} = ( \mathfrak{B}; \mathfrak{A}; \beta ; \alpha) . \]

''Proposition'' Composition of (composable) galufuncoids is a galufuncoid.

''Proof'' $( \alpha_2 \circ \alpha_1) x \sim y \Leftrightarrow \alpha_2 \alpha_1 x \sim
y \Leftrightarrow \alpha_1 x \sim \beta_2 y \Leftrightarrow x \sim \beta_1
\beta_2 y \Leftrightarrow x \sim ( \beta_1 \circ \beta_2) y$.

''Obvious'' Galufuncoids form a category (similarly to the category of pointfree funcoids).

We can define order of galufuncoids by the formula
$$f \sqsubseteq g \Leftrightarrow \forall x \in \mathfrak{A}: \langle f \rangle x \sqsubseteq \langle g \rangle x \wedge \forall y \in \mathfrak{B}: \langle f^{- 1} \rangle y \sqsubseteq \langle g^{- 1} \rangle y.$$

/***
|''Name''|TiddlySpaceTiddlerIconsPlugin|
|''Version''|0.8.10|
|''Status''|@@beta@@|
|''Author''|Jon Robson|
|''Description''|Provides ability to render SiteIcons and icons that correspond to the home location of given tiddlers|
|''Source''|http://github.com/TiddlySpace/tiddlyspace/raw/master/src/plugins/TiddlySpaceTiddlerIconsPlugin.js|
|''Requires''|TiddlySpaceConfig BinaryTiddlersPlugin ImageMacroPlugin TiddlySpacePublishingCommands|
!Notes
{{{<<tiddlerOrigin>>}}} shows the origin of the tiddler it is being run on.
In TiddlySpace terms this means it will determine whether the tiddler is external, public or private.
Where private it will analyse whether a public version exists and distinguish between the different scenarios.
If a tiddler is external, the SiteIcon of that external space will be shown

!Parameters
width / height : define a width or height of the outputted icon
label: if label parameter is set to yes, a label will accompany the icon.

/**
 * @ngdoc function
 * @name angular.element
 * @function
 *
 * @description
 * Wraps a raw DOM element or HTML string as a [jQuery](http://jquery.com) element.
 * `angular.element` can be either an alias for [jQuery](http://api.jquery.com/jQuery/) function, if
 * jQuery is available, or a function that wraps the element or string in Angular's jQuery lite
 * implementation (commonly referred to as jqLite).
 *
 * Real jQuery always takes precedence over jqLite, provided it was loaded before `DOMContentLoaded`
 * event fired.
 *
 * jqLite is a tiny, API-compatible subset of jQuery that allows
 * Angular to manipulate the DOM. jqLite implements only the most commonly needed functionality
 * within a very small footprint, so only a subset of the jQuery API - methods, arguments and
 * invocation styles - are supported.
 *
 * Note: All element references in Angular are always wrapped with jQuery or jqLite; they are never
 * raw DOM references.
 *
 * ## Angular's jqLite
 * Angular's lite version of jQuery provides only the following jQuery methods:
 *
 * - [addClass()](http://api.jquery.com/addClass/)
 * - [after()](http://api.jquery.com/after/)
 * - [append()](http://api.jquery.com/append/)
 * - [attr()](http://api.jquery.com/attr/)
 * - [bind()](http://api.jquery.com/bind/) - Does not support namespaces
 * - [children()](http://api.jquery.com/children/) - Does not support selectors
 * - [clone()](http://api.jquery.com/clone/)
 * - [contents()](http://api.jquery.com/contents/)
 * - [css()](http://api.jquery.com/css/)
 * - [data()](http://api.jquery.com/data/)
 * - [eq()](http://api.jquery.com/eq/)
 * - [find()](http://api.jquery.com/find/) - Limited to lookups by tag name
 * - [hasClass()](http://api.jquery.com/hasClass/)
 * - [html()](http://api.jquery.com/html/)
 * - [next()](http://api.jquery.com/next/) - Does not support selectors
 * - [parent()](http://api.jquery.com/parent/) - Does not support selectors
 * - [prepend()](http://api.jquery.com/prepend/)
 * - [prop()](http://api.jquery.com/prop/)
 * - [ready()](http://api.jquery.com/ready/)
 * - [remove()](http://api.jquery.com/remove/)
 * - [removeAttr()](http://api.jquery.com/removeAttr/)
 * - [removeClass()](http://api.jquery.com/removeClass/)
 * - [removeData()](http://api.jquery.com/removeData/)
 * - [replaceWith()](http://api.jquery.com/replaceWith/)
 * - [text()](http://api.jquery.com/text/)
 * - [toggleClass()](http://api.jquery.com/toggleClass/)
 * - [triggerHandler()](http://api.jquery.com/triggerHandler/) - Doesn't pass native event objects to handlers.
 * - [unbind()](http://api.jquery.com/unbind/) - Does not support namespaces
 * - [val()](http://api.jquery.com/val/)
 * - [wrap()](http://api.jquery.com/wrap/)
 *
 * ## jQuery/jqLite Extras
 * Angular also provides the following additional methods and events to both jQuery and jqLite:
 *
 * ### Events
 * - `$destroy` - AngularJS intercepts all jqLite/jQuery's DOM destruction apis and fires this event
 *    on all DOM nodes being removed.  This can be used to clean up and 3rd party bindings to the DOM
 *    element before it is removed.
 * ### Methods
 * - `controller(name)` - retrieves the controller of the current element or its parent. By default
 *   retrieves controller associated with the `ngController` directive. If `name` is provided as
 *   camelCase directive name, then the controller for this directive will be retrieved (e.g.
 *   `'ngModel'`).
 * - `injector()` - retrieves the injector of the current element or its parent.
 * - `scope()` - retrieves the {@link api/ng.$rootScope.Scope scope} of the current
 *   element or its parent.
 * - `inheritedData()` - same as `data()`, but walks up the DOM until a value is found or the top
 *   parent element is reached.
 *
 * @param {string|DOMElement} element HTML string or DOMElement to be wrapped into jQuery.
 * @returns {Object} jQuery object.

 * # Injection Function Annotation
 *
 * JavaScript does not have annotations, and annotations are needed for dependency injection. The
 * following are all valid ways of annotating function with injection arguments and are equivalent.
 *
 * <pre>
 *   // inferred (only works if code not minified/obfuscated)
 *   $injector.invoke(function(serviceA){});

 *   // annotated
 *   function explicit(serviceA) {};

 *
 *   // inline
 *   $injector.invoke(['serviceA', function(serviceA){}]);
 * </pre>
 *
 * ## Inference
 *
 * In JavaScript calling `toString()` on a function returns the function definition. The definition can then be
 * parsed and the function arguments can be extracted. *NOTE:* This does not work with minification, and obfuscation
 * tools since these tools change the argument names.
 *
 * ## `$inject` Annotation
 * By adding a `$inject` property onto a function the injection parameters can be specified.
 *
 * ## Inline
 * As an array of injection names, where the last item in the array is the function to call.

/**

 * @methodOf AUTO.$injector
 *
 * @description
 * Returns an array of service names which the function is requesting for injection. This API is used by the injector
 * to determine which services need to be injected into the function when the function is invoked. There are three
 * ways in which the function can be annotated with the needed dependencies.
 *
 * # Argument names
 *
 * The simplest form is to extract the dependencies from the arguments of the function. This is done by converting
 * the function into a string using `toString()` method and extracting the argument names.
 * <pre>
 *   // Given
 *   function MyController($scope, $route) {
 *     // ...
 *   }
 *
 *   // Then
 *   expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
 * </pre>
 *
 * This method does not work with code minfication / obfuscation. For this reason the following annotation strategies
 * are supported.
 *
 * # The `$inject` property
 *
 * If a function has an `$inject` property and its value is an array of strings, then the strings represent names of
 * services to be injected into the function.
 * <pre>
 *   // Given
 *   var MyController = function(obfuscatedScope, obfuscatedRoute) {
 *     // ...
 *   }
 *   // Define function dependencies
 *   MyController.$inject = ['$scope', '$route'];
 *
 *   // Then
 *   expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
 * </pre>
 *
 * # The array notation
 *
 * It is often desirable to inline Injected functions and that's when setting the `$inject` property is very
 * inconvenient. In these situations using the array notation to specify the dependencies in a way that survives
 * minification is a better choice:
 *
 * <pre>
 *   // We wish to write this (not minification / obfuscation safe)
 *   injector.invoke(function($compile, $rootScope) {
 *     // ...
 *   });
 *
 *   // We are forced to write break inlining
 *   var tmpFn = function(obfuscatedCompile, obfuscatedRootScope) {
 *     // ...
 *   };
 *   tmpFn.$inject = ['$compile', '$rootScope'];
 *   injector.invoke(tmpFn);
 *
 *   // To better support inline function the inline annotation is supported
 *   injector.invoke(['$compile', '$rootScope', function(obfCompile, obfRootScope) {
 *     // ...
 *   }]);
 *
 *   // Therefore
 *   expect(injector.annotate(
 *      ['$compile', '$rootScope', function(obfus_$compile, obfus_$rootScope) {}])
 *    ).toEqual(['$compile', '$rootScope']);
 * </pre>
 *
 * @param {function|Array.<string|Function>} fn Function for which dependent service names need to be retrieved as described
 *   above.
 *
 * @returns {Array.<string>} The names of the services which the function requires.

 *

 *
 *
 * @param {string|DOMElement} element Element or HTML string to compile into a template function.
 * @param {function(angular.Scope[, cloneAttachFn]} transclude function available to directives.
 * @param {number} maxPriority only apply directives lower then given priority (Only effects the
 *                 root element(s), not their children)
 * @returns {function(scope[, cloneAttachFn])} a link function which is used to bind template
 * (a DOM element/tree) to a scope. Where:
 *
 *  * `scope` - A {@link ng.$rootScope.Scope Scope} to bind to.
 *  * `cloneAttachFn` - If `cloneAttachFn` is provided, then the link function will clone the
 *               `template` and call the `cloneAttachFn` function allowing the caller to attach the
 *               cloned elements to the DOM document at the appropriate place. The `cloneAttachFn` is
 *               called as: <br> `cloneAttachFn(clonedElement, scope)` where:
 *
 *      * `clonedElement` - is a clone of the original `element` passed into the compiler.
 *      * `scope` - is the current scope with which the linking function is working with.
 *
 * Calling the linking function returns the element of the template. It is either the original element
 * passed in, or the clone of the element if the `cloneAttachFn` is provided.
 *
 * After linking the view is not updated until after a call to $digest which typically is done by
 * Angular automatically.
 *
 * If you need access to the bound view, there are two ways to do it:
 *
 * - If you are not asking the linking function to clone the template, create the DOM element(s)
 *   before you send them to the compiler and keep this reference around.
 *   <pre>
 *     var element = $compile('<p>{{total}}</p>')(scope);
 *   </pre>
 *
 * - if on the other hand, you need the element to be cloned, the view reference from the original
 *   example would not point to the clone, but rather to the original template that was cloned. In
 *   this case, you can access the clone via the cloneAttachFn:
 *   <pre>
 *     var templateHTML = angular.element('<p>{{total}}</p>'),
 *         scope = ....;
 *
 *     var clonedElement = $compile(templateHTML)(scope, function(clonedElement, scope) {
 *       //attach the clone to DOM document at the right place
 *     });
 *
 *     //now we have reference to the cloned DOM via `clone`
 *   </pre>
 *
 *
 * For information on how the compiler works, see the
 * {@link guide/compiler Angular HTML Compiler} section of the Developer Guide.

/**
 * @ngdoc service
 * @name ng.$q
 * @requires $rootScope
 *
 * @description
 * A promise/deferred implementation inspired by [Kris Kowal's Q](https://github.com/kriskowal/q).
 *
 * [The CommonJS Promise proposal](http://wiki.commonjs.org/wiki/Promises) describes a promise as an
 * interface for interacting with an object that represents the result of an action that is
 * performed asynchronously, and may or may not be finished at any given point in time.
 *
 * From the perspective of dealing with error handling, deferred and promise APIs are to
 * asynchronous programming what `try`, `catch` and `throw` keywords are to synchronous programming.
 *
 * <pre>
 *   // for the purpose of this example let's assume that variables `$q` and `scope` are
 *   // available in the current lexical scope (they could have been injected or passed in).
 *
 *   function asyncGreet(name) {
 *     var deferred = $q.defer();
 *
 *     setTimeout(function() {
 *       // since this fn executes async in a future turn of the event loop, we need to wrap
 *       // our code into an $apply call so that the model changes are properly observed.
 *       scope.$apply(function() {
 *         if (okToGreet(name)) {
 *           deferred.resolve('Hello, ' + name + '!');
 *         } else {
 *           deferred.reject('Greeting ' + name + ' is not allowed.');
 *         }
 *       });
 *     }, 1000);
 *
 *     return deferred.promise;
 *   }
 *
 *   var promise = asyncGreet('Robin Hood');
 *   promise.then(function(greeting) {
 *     alert('Success: ' + greeting);
 *   }, function(reason) {
 *     alert('Failed: ' + reason);
 *   });
 * </pre>
 *
 * At first it might not be obvious why this extra complexity is worth the trouble. The payoff
 * comes in the way of
 * [guarantees that promise and deferred APIs make](https://github.com/kriskowal/uncommonjs/blob/master/promises/specification.md).
 *
 * Additionally the promise api allows for composition that is very hard to do with the
 * traditional callback ([CPS](http://en.wikipedia.org/wiki/Continuation-passing_style)) approach.
 * For more on this please see the [Q documentation](https://github.com/kriskowal/q) especially the
 * section on serial or parallel joining of promises.
 *
 *
 * # The Deferred API
 *
 * A new instance of deferred is constructed by calling `$q.defer()`.
 *
 * The purpose of the deferred object is to expose the associated Promise instance as well as APIs
 * that can be used for signaling the successful or unsuccessful completion of the task.
 *
 * **Methods**
 *
 * - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection
 *   constructed via `$q.reject`, the promise will be rejected instead.
 * - `reject(reason)` – rejects the derived promise with the `reason`. This is equivalent to
 *   resolving it with a rejection constructed via `$q.reject`.
 *
 * **Properties**
 *
 * - promise – `{Promise}` – promise object associated with this deferred.
 *
 *
 * # The Promise API
 *
 * A new promise instance is created when a deferred instance is created and can be retrieved by
 * calling `deferred.promise`.
 *
 * The purpose of the promise object is to allow for interested parties to get access to the result
 * of the deferred task when it completes.
 *
 * **Methods**
 *
 * - `then(successCallback, errorCallback)` – regardless of when the promise was or will be resolved
 *   or rejected, `then` calls one of the success or error callbacks asynchronously as soon as the result
 *   is available. The callbacks are called with a single argument: the result or rejection reason.
 *
 *   This method *returns a new promise* which is resolved or rejected via the return value of the
 *   `successCallback` or `errorCallback`.
 *
 *
 * # Chaining promises
 *
 * Because calling the `then` method of a promise returns a new derived promise, it is easily possible
 * to create a chain of promises:
 *
 * <pre>
 *   promiseB = promiseA.then(function(result) {
 *     return result + 1;
 *   });
 *
 *   // promiseB will be resolved immediately after promiseA is resolved and its value
 *   // will be the result of promiseA incremented by 1
 * </pre>
 *
 * It is possible to create chains of any length and since a promise can be resolved with another
 * promise (which will defer its resolution further), it is possible to pause/defer resolution of
 * the promises at any point in the chain. This makes it possible to implement powerful APIs like
 * $http's response interceptors.
 *
 *
 * # Differences between Kris Kowal's Q and $q
 *
 *  There are three main differences:
 *
 * - $q is integrated with the {@link ng.$rootScope.Scope} Scope model observation
 *   mechanism in angular, which means faster propagation of resolution or rejection into your
 *   models and avoiding unnecessary browser repaints, which would result in flickering UI.
 * - $q promises are recognized by the templating engine in angular, which means that in templates
 *   you can treat promises attached to a scope as if they were the resulting values.
 * - Q has many more features than $q, but that comes at a cost of bytes. $q is tiny, but contains
 *   all the important functionality needed for common async tasks.
 * 
 *  # Testing
 * 
 *  <pre>
 *    it('should simulate promise', inject(function($q, $rootScope) {
 *      var deferred = $q.defer();
 *      var promise = deferred.promise;
 *      var resolvedValue;
 * 
 *      promise.then(function(value) { resolvedValue = value; });
 *      expect(resolvedValue).toBeUndefined();
 * 
 *      // Simulate resolving of promise
 *      deferred.resolve(123);
 *      // Note that the 'then' function does not get called synchronously.
 *      // This is because we want the promise API to always be async, whether or not
 *      // it got called synchronously or asynchronously.
 *      expect(resolvedValue).toBeUndefined();
 * 
 *      // Propagate promise resolution to 'then' functions using $apply().
 *      $rootScope.$apply();
 *      expect(resolvedValue).toEqual(123);
 *    });

   *    contains redundant trailing slash or is missing one, the route will still match and the
   *    `$location.path` will be updated to add or drop the trailing slash to exactly match the
   *    route definition.

   *    `path` can contain named groups starting with a colon (`:name`). All characters up to the
   *    next slash are matched and stored in `$routeParams` under the given `name` after the route
   *    is resolved.
   *
   * @param {Object} route Mapping information to be assigned to `$route.current` on route
   *    match.
   *
   *    Object properties:

   *      created scope or the name of a {@link angular.Module#controller registered controller}
   *      if passed as a string.
   *    - `template` – `{string=}` –  html template as a string that should be used by
   *      {@link ng.directive:ngView ngView} or
   *      {@link ng.directive:ngInclude ngInclude} directives.
   *      this property takes precedence over `templateUrl`.
   *    - `templateUrl` – `{string=}` – path to an html template that should be used by
   *      {@link ng.directive:ngView ngView}.
   *    - `resolve` - `{Object.<string, function>=}` - An optional map of dependencies which should
   *      be injected into the controller. If any of these dependencies are promises, they will be
   *      resolved and converted to a value before the controller is instantiated and the
   *      `$routeChangeSuccess` event is fired. The map object is:
   *
   *      - `key` – `{string}`: a name of a dependency to be injected into the controller.
   *      - `factory` - `{string|function}`: If `string` then it is an alias for a service.
   *        Otherwise if function, then it is {@link api/AUTO.$injector#invoke injected}
   *        and the return value is treated as the dependency. If the result is a promise, it is resolved
   *        before its value is injected into the controller. Be aware that `ngRoute.$routeParams` will
   *        still refer to the previous route within these resolve functions.  Use `$route.current.params`
   *        to access the new route parameters, instead.
   *
   *    - `redirectTo` – {(string|function())=} – value to update
   *      {@link ng.$location $location} path with and trigger route redirection.
   *
   *      If `redirectTo` is a function, it will be called with the following parameters:
   *
   *      - `{Object.<string>}` - route parameters extracted from the current
   *        `$location.path()` by applying the current route templateUrl.
   *      - `{string}` - current `$location.path()`
   *      - `{Object}` - current `$location.search()`
   *
   *      The custom `redirectTo` function is expected to return a string which will be used
   *      to update `$location.path()` and `$location.search()`.
   *
   *    - `[reloadOnSearch=true]` - {boolean=} - reload route when only $location.search()
   *    changes.
   *
   *      If the option is set to `false` and url in the browser changes, then
   *      `$routeUpdate` event is broadcasted on the root scope.

/**
 * @ngdoc object
 * @name ng.$routeParams
 * @requires $route
 *
 * @description
 * Current set of route parameters. The route parameters are a combination of the
 * {@link ng.$location $location} `search()`, and `path()`. The `path` parameters
 * are extracted when the {@link ng.$route $route} path is matched.
 *
 * In case of parameter name collision, `path` params take precedence over `search` params.
 *
 * The service guarantees that the identity of the `$routeParams` object will remain unchanged
 * (but its properties will likely change) even when a route change occurs.
 *
 * Note that the `$routeParams` are only updated *after* a route change completes successfully.
 * This means that you cannot rely on `$routeParams` being correct in route resolve functions.
 * Instead you can use `$route.current.params` to access the new route's parameters.
 *
 * @example
 * <pre>
 *  // Given:
 *  // URL: http://server.com/index.html#/Chapter/1/Section/2?search=moby
 *  // Route: /Chapter/:chapterId/Section/:sectionId

/**
 * DESIGN NOTES
 *
 * The design decisions behind the scope are heavily favored for speed and memory consumption.
 *
 * The typical use of scope is to watch the expressions, which most of the time return the same
 * value as last time so we optimize the operation.
 *
 * Closures construction is expensive in terms of speed as well as memory:
 *   - No closures, instead use prototypical inheritance for API
 *   - Internal state needs to be stored on scope directly, which means that private state is
 *     exposed as $$____ properties
 *
 * Loop operations are optimized by using while(count--) { ... }
 *   - this means that in order to keep the same order of execution as addition we have to add
 *     items to the array at the beginning (shift) instead of at the end (push)
 *
 * Child scopes are created and removed often
 *   - Using an array would be slow since inserts in middle are expensive so we use linked list
 *
 * There are few watches then a lot of observers. This is why you don't want the observer to be
 * implemented in the same way as watch. Watch requires return of initialization function which
 * are expensive to construct.

       * Registers a `listener` callback to be executed whenever the `watchExpression` changes.
       *
       * - The `watchExpression` is called on every call to {@link ng.$rootScope.Scope#$digest $digest()} and
       *   should return the value which will be watched. (Since {@link ng.$rootScope.Scope#$digest $digest()}
       *   reruns when it detects changes the `watchExpression` can execute multiple times per
       *   {@link ng.$rootScope.Scope#$digest $digest()} and should be idempotent.)
       * - The `listener` is called only when the value from the current `watchExpression` and the
       *   previous call to `watchExpression` are not equal (with the exception of the initial run,
       *   see below). The inequality is determined according to
       *   {@link angular.equals} function. To save the value of the object for later comparison, the
       *   {@link angular.copy} function is used. It also means that watching complex options will
       *   have adverse memory and performance implications.
       * - The watch `listener` may change the model, which may trigger other `listener`s to fire. This
       *   is achieved by rerunning the watchers until no changes are detected. The rerun iteration
       *   limit is 10 to prevent an infinite loop deadlock.
       *
       *
       * If you want to be notified whenever {@link ng.$rootScope.Scope#$digest $digest} is called,
       * you can register a `watchExpression` function with no `listener`. (Since `watchExpression`
       * can execute multiple times per {@link ng.$rootScope.Scope#$digest $digest} cycle when a change is
       * detected, be prepared for multiple calls to your listener.)
       *
       * After a watcher is registered with the scope, the `listener` fn is called asynchronously
       * (via {@link ng.$rootScope.Scope#$evalAsync $evalAsync}) to initialize the
       * watcher. In rare cases, this is undesirable because the listener is called when the result
       * of `watchExpression` didn't change. To detect this scenario within the `listener` fn, you
       * can compare the `newVal` and `oldVal`. If these two values are identical (`===`) then the
       * listener was called due to initialization.
       *

     * that is used to generate an HTTP request and returns  a {@link ng.$q promise}
     * with two $http specific methods: `success` and `error`.
     *
     * <pre>
     *   $http({method: 'GET', url: '/someUrl'}).
     *     success(function(data, status, headers, config) {
     *       // this callback will be called asynchronously
     *       // when the response is available
     *     }).
     *     error(function(data, status, headers, config) {
     *       // called asynchronously if an error occurs
     *       // or server returns response with an error status.
     *     });
     * </pre>
     *
     * Since the returned value of calling the $http function is a `promise`, you can also use
     * the `then` method to register callbacks, and these callbacks will receive a single argument –
     * an object representing the response. See the API signature and type info below for more
     * details.
     *
     * A response status code between 200 and 299 is considered a success status and
     * will result in the success callback being called. Note that if the response is a redirect,
     * XMLHttpRequest will transparently follow it, meaning that the error callback will not be
     * called for such responses.
     *
     * # Shortcut methods
     *
     * Since all invocations of the $http service require passing in an HTTP method and URL, and
     * POST/PUT requests require request data to be provided as well, shortcut methods
     * were created:
     *
     * <pre>
     *   $http.get('/someUrl').success(successCallback);
     *   $http.post('/someUrl', data).success(successCallback);
     * </pre>
     *
     * Complete list of shortcut methods:
     *
     * - {@link ng.$http#get $http.get}
     * - {@link ng.$http#head $http.head}
     * - {@link ng.$http#post $http.post}
     * - {@link ng.$http#put $http.put}
     * - {@link ng.$http#delete $http.delete}
     * - {@link ng.$http#jsonp $http.jsonp}
     *
     *
     * # Setting HTTP Headers
     *
     * The $http service will automatically add certain HTTP headers to all requests. These defaults
     * can be fully configured by accessing the `$httpProvider.defaults.headers` configuration
     * object, which currently contains this default configuration:
     *
     * - `$httpProvider.defaults.headers.common` (headers that are common for all requests):
     *   - `Accept: application/json, text/plain, * / *`
     *   - `X-Requested-With: XMLHttpRequest`
     * - `$httpProvider.defaults.headers.post`: (header defaults for POST requests)
     *   - `Content-Type: application/json`
     * - `$httpProvider.defaults.headers.put` (header defaults for PUT requests)
     *   - `Content-Type: application/json`
     *
     * To add or overwrite these defaults, simply add or remove a property from these configuration
     * objects. To add headers for an HTTP method other than POST or PUT, simply add a new object
     * with the lowercased HTTP method name as the key, e.g.
     * `$httpProvider.defaults.headers.get['My-Header']='value'`.
     *
     * Additionally, the defaults can be set at runtime via the `$http.defaults` object in the same
     * fashion.
     *
     *
     * # Transforming Requests and Responses
     *
     * Both requests and responses can be transformed using transform functions. By default, Angular
     * applies these transformations:
     *
     * Request transformations:
     *
     * - If the `data` property of the request configuration object contains an object, serialize it into
     *   JSON format.
     *
     * Response transformations:
     *
     *  - If XSRF prefix is detected, strip it (see Security Considerations section below).
     *  - If JSON response is detected, deserialize it using a JSON parser.
     *
     * To globally augment or override the default transforms, modify the `$httpProvider.defaults.transformRequest` and
     * `$httpProvider.defaults.transformResponse` properties. These properties are by default an
     * array of transform functions, which allows you to `push` or `unshift` a new transformation function into the
     * transformation chain. You can also decide to completely override any default transformations by assigning your
     * transformation functions to these properties directly without the array wrapper.
     *
     * Similarly, to locally override the request/response transforms, augment the `transformRequest` and/or
     * `transformResponse` properties of the configuration object passed into `$http`.
     *
     *
     * # Caching
     *
     * To enable caching, set the configuration property `cache` to `true`. When the cache is
     * enabled, `$http` stores the response from the server in local cache. Next time the
     * response is served from the cache without sending a request to the server.
     *
     * Note that even if the response is served from cache, delivery of the data is asynchronous in
     * the same way that real requests are.
     *
     * If there are multiple GET requests for the same URL that should be cached using the same
     * cache, but the cache is not populated yet, only one request to the server will be made and
     * the remaining requests will be fulfilled using the response from the first request.
     *
     *
     * # Response interceptors
     *
     * Before you start creating interceptors, be sure to understand the
     * {@link ng.$q $q and deferred/promise APIs}.
     *
     * For purposes of global error handling, authentication or any kind of synchronous or
     * asynchronous preprocessing of received responses, it is desirable to be able to intercept
     * responses for http requests before they are handed over to the application code that
     * initiated these requests. The response interceptors leverage the {@link ng.$q
     * promise apis} to fulfil this need for both synchronous and asynchronous preprocessing.
     *
     * The interceptors are service factories that are registered with the $httpProvider by
     * adding them to the `$httpProvider.responseInterceptors` array. The factory is called and
     * injected with dependencies (if specified) and returns the interceptor  — a function that
     * takes a {@link ng.$q promise} and returns the original or a new promise.
     *
     * <pre>
     *   // register the interceptor as a service
     *   $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) {
     *     return function(promise) {
     *       return promise.then(function(response) {
     *         // do something on success
     *         return response;
     *       }, function(response) {
     *         // do something on error
     *         if (canRecover(response)) {
     *           return responseOrNewPromise
     *         }
     *         return $q.reject(response);
     *       });
     *     }
     *   });
     *
     *   $httpProvider.responseInterceptors.push('myHttpInterceptor');
     *
     *
     *   // register the interceptor via an anonymous factory
     *   $httpProvider.responseInterceptors.push(function($q, dependency1, dependency2) {
     *     return function(promise) {
     *       // same as above
     *     }
     *   });
     * </pre>
     *
     *
     * # Security Considerations
     *
     * When designing web applications, consider security threats from:
     *
     * - {@link http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx
     *   JSON vulnerability}
     * - {@link http://en.wikipedia.org/wiki/Cross-site_request_forgery XSRF}
     *
     * Both server and the client must cooperate in order to eliminate these threats. Angular comes
     * pre-configured with strategies that address these issues, but for this to work backend server
     * cooperation is required.
     *
     * ## JSON Vulnerability Protection
     *
     * A {@link http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx
     * JSON vulnerability} allows third party website to turn your JSON resource URL into
     * {@link http://en.wikipedia.org/wiki/JSONP JSONP} request under some conditions. To
     * counter this your server can prefix all JSON requests with following string `")]}',\n"`.
     * Angular will automatically strip the prefix before processing it as JSON.
     *
     * For example if your server needs to return:
     * <pre>
     * ['one','two']
     * </pre>
     *
     * which is vulnerable to attack, your server can return:
     * <pre>
     * )]}',
     * ['one','two']
     * </pre>
     *
     * Angular will strip the prefix, before processing the JSON.
     *
     *
     * ## Cross Site Request Forgery (XSRF) Protection
     *
     * {@link http://en.wikipedia.org/wiki/Cross-site_request_forgery XSRF} is a technique by which
     * an unauthorized site can gain your user's private data. Angular provides a mechanism
     * to counter XSRF. When performing XHR requests, the $http service reads a token from a cookie
     * called `XSRF-TOKEN` and sets it as the HTTP header `X-XSRF-TOKEN`. Since only JavaScript that
     * runs on your domain could read the cookie, your server can be assured that the XHR came from
     * JavaScript running on your domain.
     *
     * To take advantage of this, your server needs to set a token in a JavaScript readable session
     * cookie called `XSRF-TOKEN` on the first HTTP GET request. On subsequent XHR requests the
     * server can verify that the cookie matches `X-XSRF-TOKEN` HTTP header, and therefore be sure
     * that only JavaScript running on your domain could have sent the request. The token must be
     * unique for each user and must be verifiable by the server (to prevent the JavaScript from making
     * up its own tokens). We recommend that the token is a digest of your site's authentication
     * cookie with a {@link https://en.wikipedia.org/wiki/Salt_(cryptography) salt} for added security.
     *
     *
     * @param {object} config Object describing the request to be made and how it should be
     *    processed. The object has following properties:
     *
     *    - **method** – `{string}` – HTTP method (e.g. 'GET', 'POST', etc)
     *    - **url** – `{string}` – Absolute or relative URL of the resource that is being requested.
     *    - **params** – `{Object.<string|Object>}` – Map of strings or objects which will be turned to
     *      `?key1=value1&key2=value2` after the url. If the value is not a string, it will be JSONified.
     *    - **data** – `{string|Object}` – Data to be sent as the request message data.
     *    - **headers** – `{Object}` – Map of strings representing HTTP headers to send to the server.
     *    - **transformRequest** – `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –
     *      transform function or an array of such functions. The transform function takes the http
     *      request body and headers and returns its transformed (typically serialized) version.
     *    - **transformResponse** – `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –
     *      transform function or an array of such functions. The transform function takes the http
     *      response body and headers and returns its transformed (typically deserialized) version.
     *    - **cache** – `{boolean|Cache}` – If true, a default $http cache will be used to cache the
     *      GET request, otherwise if a cache instance built with
     *      {@link ng.$cacheFactory $cacheFactory}, this cache will be used for
     *      caching.
     *    - **timeout** – `{number}` – timeout in milliseconds.
     *    - **withCredentials** - `{boolean}` - whether to to set the `withCredentials` flag on the
     *      XHR object. See {@link https://developer.mozilla.org/en/http_access_control#section_5
     *      requests with credentials} for more information.
     *
     * @returns {HttpPromise} Returns a {@link ng.$q promise} object with the
     *   standard `then` method and two http specific methods: `success` and `error`. The `then`
     *   method takes two arguments a success and an error callback which will be called with a
     *   response object. The `success` and `error` methods take a single argument - a function that
     *   will be called when the request succeeds or fails respectively. The arguments passed into
     *   these functions are destructured representation of the response object passed into the
     *   `then` method. The response object has these properties:
     *
     *   - **data** – `{string|Object}` – The response body transformed with the transform functions.
     *   - **status** – `{number}` – HTTP status code of the response.
     *   - **headers** – `{function([headerName])}` – Header getter function.
     *   - **config** – `{Object}` – The configuration object that was used to generate the request.
     *
     * @property {Array.<Object>} pendingRequests Array of config objects for currently pending
     *   requests. This is primarily meant to be used for debugging purposes.

/**
 * @ngdoc filter
 * @name ng.filter:filter
 * @function
 *
 * @description
 * Selects a subset of items from `array` and returns it as a new array.
 *
 * Note: This function is used to augment the `Array` type in Angular expressions. See
 * {@link ng.$filter} for more information about Angular arrays.
 *
 * @param {Array} array The source array.
 * @param {string|Object|function()} expression The predicate to be used for selecting items from
 *   `array`.
 *
 *   Can be one of:
 *
 *   - `string`: Predicate that results in a substring match using the value of `expression`
 *     string. All strings or objects with string properties in `array` that contain this string
 *     will be returned. The predicate can be negated by prefixing the string with `!`.
 *
 *   - `Object`: A pattern object can be used to filter specific properties on objects contained
 *     by `array`. For example `{name:"M", phone:"1"}` predicate will return an array of items
 *     which have property `name` containing "M" and property `phone` containing "1". A special
 *     property name `$` can be used (as in `{$:"text"}`) to accept a match against any
 *     property of the object. That's equivalent to the simple substring match with a `string`
 *     as described above.
 *
 *   - `function`: A predicate function can be used to write arbitrary filters. The function is
 *     called for each element of `array`. The final result is an array of those elements that
 *     the predicate returned true for.

/**
 * @ngdoc filter
 * @name ng.filter:date
 * @function
 *
 * @description
 *   Formats `date` to a string based on the requested `format`.
 *
 *   `format` string can be composed of the following elements:
 *
 *   * `'yyyy'`: 4 digit representation of year (e.g. AD 1 => 0001, AD 2010 => 2010)
 *   * `'yy'`: 2 digit representation of year, padded (00-99). (e.g. AD 2001 => 01, AD 2010 => 10)
 *   * `'y'`: 1 digit representation of year, e.g. (AD 1 => 1, AD 199 => 199)
 *   * `'MMMM'`: Month in year (January-December)
 *   * `'MMM'`: Month in year (Jan-Dec)
 *   * `'MM'`: Month in year, padded (01-12)
 *   * `'M'`: Month in year (1-12)
 *   * `'dd'`: Day in month, padded (01-31)
 *   * `'d'`: Day in month (1-31)
 *   * `'EEEE'`: Day in Week,(Sunday-Saturday)
 *   * `'EEE'`: Day in Week, (Sun-Sat)
 *   * `'HH'`: Hour in day, padded (00-23)
 *   * `'H'`: Hour in day (0-23)
 *   * `'hh'`: Hour in am/pm, padded (01-12)
 *   * `'h'`: Hour in am/pm, (1-12)
 *   * `'mm'`: Minute in hour, padded (00-59)
 *   * `'m'`: Minute in hour (0-59)
 *   * `'ss'`: Second in minute, padded (00-59)
 *   * `'s'`: Second in minute (0-59)
 *   * `'a'`: am/pm marker
 *   * `'Z'`: 4 digit (+sign) representation of the timezone offset (-1200-+1200)
 *
 *   `format` string can also be one of the following predefined
 *   {@link guide/i18n localizable formats}:
 *
 *   * `'medium'`: equivalent to `'MMM d, y h:mm:ss a'` for en_US locale
 *     (e.g. Sep 3, 2010 12:05:08 pm)
 *   * `'short'`: equivalent to `'M/d/yy h:mm a'` for en_US  locale (e.g. 9/3/10 12:05 pm)
 *   * `'fullDate'`: equivalent to `'EEEE, MMMM d,y'` for en_US  locale
 *     (e.g. Friday, September 3, 2010)
 *   * `'longDate'`: equivalent to `'MMMM d, y'` for en_US  locale (e.g. September 3, 2010)
 *   * `'mediumDate'`: equivalent to `'MMM d, y'` for en_US  locale (e.g. Sep 3, 2010)
 *   * `'shortDate'`: equivalent to `'M/d/yy'` for en_US locale (e.g. 9/3/10)
 *   * `'mediumTime'`: equivalent to `'h:mm:ss a'` for en_US locale (e.g. 12:05:08 pm)
 *   * `'shortTime'`: equivalent to `'h:mm a'` for en_US locale (e.g. 12:05 pm)
 *
 *   `format` string can contain literal values. These need to be quoted with single quotes (e.g.
 *   `"h 'in the morning'"`). In order to output single quote, use two single quotes in a sequence
 *   (e.g. `"h 'o''clock'"`).
 *
 * @param {(Date|number|string)} date Date to format either as Date object, milliseconds (string or
 *    number) or various ISO 8601 datetime string formats (e.g. yyyy-MM-ddTHH:mm:ss.SSSZ and its
 *    shorter versions like yyyy-MM-ddTHH:mmZ, yyyy-MM-dd or yyyyMMddTHHmmssZ). If no timezone is
 *    specified in the string input, the time is considered to be in the local timezone.
 * @param {string=} format Formatting rules (see Description). If not specified,
 *    `mediumDate` is used.
 * @returns {string} Formatted string or the input if input is not recognized as date/millis.

/**
 * @ngdoc function
 * @name ng.filter:orderBy
 * @function
 *
 * @description
 * Orders a specified `array` by the `expression` predicate.
 *
 * Note: this function is used to augment the `Array` type in Angular expressions. See
 * {@link ng.$filter} for more informaton about Angular arrays.
 *
 * @param {Array} array The array to sort.
 * @param {function(*)|string|Array.<(function(*)|string)>} expression A predicate to be
 *    used by the comparator to determine the order of elements.
 *
 *    Can be one of:
 *
 *    - `function`: Getter function. The result of this function will be sorted using the
 *      `<`, `=`, `>` operator.
 *    - `string`: An Angular expression which evaluates to an object to order by, such as 'name'
 *      to sort by a property called 'name'. Optionally prefixed with `+` or `-` to control
 *      ascending or descending sort order (for example, +name or -name).
 *    - `Array`: An array of function or string predicates. The first predicate in the array
 *      is used for sorting, but when two items are equivalent, the next predicate is used.
 *
 * @param {boolean=} reverse Reverse the order the array.
 * @returns {Array} Sorted copy of the source array.

 /**
 * @ngdoc directive
 * @name ng.directive:form
 * @restrict E
 *
 * @description
 * Directive that instantiates
 * {@link ng.directive:form.FormController FormController}.
 *
 * If `name` attribute is specified, the form controller is published onto the current scope under
 * this name.
 *
 * # Alias: {@link ng.directive:ngForm `ngForm`}
 *
 * In angular forms can be nested. This means that the outer form is valid when all of the child
 * forms are valid as well. However browsers do not allow nesting of `<form>` elements, for this
 * reason angular provides {@link ng.directive:ngForm `ngForm`} alias
 * which behaves identical to `<form>` but allows form nesting.
 *
 *
 * # CSS classes
 *  - `ng-valid` Is set if the form is valid.
 *  - `ng-invalid` Is set if the form is invalid.
 *  - `ng-pristine` Is set if the form is pristine.
 *  - `ng-dirty` Is set if the form is dirty.
 *
 *
 * # Submitting a form and preventing default action
 *
 * Since the role of forms in client-side Angular applications is different than in classical
 * roundtrip apps, it is desirable for the browser not to translate the form submission into a full
 * page reload that sends the data to the server. Instead some javascript logic should be triggered
 * to handle the form submission in application specific way.
 *
 * For this reason, Angular prevents the default action (form submission to the server) unless the
 * `<form>` element has an `action` attribute specified.
 *
 * You can use one of the following two ways to specify what javascript method should be called when
 * a form is submitted:
 *
 * - {@link ng.directive:ngSubmit ngSubmit} directive on the form element
 * - {@link ng.directive:ngClick ngClick} directive on the first
  *  button or input field of type submit (input[type=submit])
 *
 * To prevent double execution of the handler, use only one of ngSubmit or ngClick directives. This
 * is because of the following form submission rules coming from the html spec:
 *
 * - If a form has only one input field then hitting enter in this field triggers form submit
 * (`ngSubmit`)
 * - if a form has has 2+ input fields and no buttons or input[type=submit] then hitting enter
 * doesn't trigger submit
 * - if a form has one or more input fields and one or more buttons or input[type=submit] then
 * hitting enter in any of the input fields will trigger the click handler on the *first* button or
 * input[type=submit] (`ngClick`) *and* a submit handler on the enclosing form (`ngSubmit`)
 *
 * @param {string=} name Name of the form. If specified, the form controller will be published into
 *                       related scope, under this name.

 *
 * `NgModelController` provides API for the `ng-model` directive. The controller contains
 * services for data-binding, validation, CSS update, value formatting and parsing. It
 * specifically does not contain any logic which deals with DOM rendering or listening to
 * DOM events. The `NgModelController` is meant to be extended by other directives where, the
 * directive provides DOM manipulation and the `NgModelController` provides the data-binding.
 * Note that you cannot use `NgModelController` in a directive with an isolated scope,
 * as, in that case, the `ng-model` value gets put into the isolated scope and does not get
 * propogated to the parent scope.
 *
 *
 * This example shows how to use `NgModelController` with a custom control to achieve
 * data-binding. Notice how different directives (`contenteditable`, `ng-model`, and `required`)
 * collaborate together to achieve the desired result.
 *
 * <example module="customControl">
    <file name="style.css">
      [contenteditable] {
        border: 1px solid black;
        background-color: white;
        min-height: 20px;
      }

      .ng-invalid {
        border: 1px solid red;
      }

    </file>
    <file name="script.js">
      angular.module('customControl', []).

          return {
            restrict: 'A', // only activate on element attribute
            require: '?ngModel', // get a hold of NgModelController
            link: function(scope, element, attrs, ngModel) {
              if(!ngModel) return; // do nothing if no ng-model

              // Specify how UI should be updated
              ngModel.$render = function() {
                element.html(ngModel.$viewValue || '');
              };

              // Listen for change events to enable binding

 * @element input
 *
 * @description
 * Is a directive that tells Angular to do two-way data binding. It works together with `input`,
 * `select`, `textarea`. You can easily write your own directives to use `ngModel` as well.
 *
 * `ngModel` is responsible for:
 *
 * - binding the view into the model, which other directives such as `input`, `textarea` or `select`
 *   require,
 * - providing validation behavior (i.e. required, number, email, url),
 * - keeping state of the control (valid/invalid, dirty/pristine, validation errors),
 * - setting related css class onto the element (`ng-valid`, `ng-invalid`, `ng-dirty`, `ng-pristine`),
 * - register the control with parent {@link ng.directive:form form}.
 *
 * Note: `ngModel` will try to bind to the property given by evaluating the expression on the
 * current scope. If the property doesn't already exist on this scope, it will be created
 * implicitly and added to the scope.
 *
 * For basic examples, how to use `ngModel`, see:
 *
 *  - {@link ng.directive:input input}
 *    - {@link ng.directive:input.text text}
 *    - {@link ng.directive:input.checkbox checkbox}
 *    - {@link ng.directive:input.radio radio}
 *    - {@link ng.directive:input.number number}
 *    - {@link ng.directive:input.email email}

 *
 * It is preferrable to use `ngBind` instead of `{{ expression }}` when a template is momentarily
