*
* @description
* The `md-icon` directive makes it easier to use vector-based icons in your app (as opposed to
* raster-based icons types like PNG). The directive supports both icon fonts and SVG icons.
*
* Icons should be considered view-only elements that should not be used directly as buttons; instead nest a `<md-icon>`
* inside a `md-button` to add hover and click features.
*
* ### Icon fonts
* Icon fonts are a technique in which you use a font where the glyphs in the font are
* your icons instead of text. Benefits include a straightforward way to bundle everything into a
* single HTTP request, simple scaling, easy color changing, and more.
*
* `md-icon` lets you consume an icon font by letting you reference specific icons in that font
* by name rather than character code.
*
* When using font-icons, developers must follow three (3) simple steps:
*
* <ol>
* <li>Load the font library. e.g.<br/>
* `<link href="https://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet">`
* </li>
* <li>
* Use either (a) font-icon class names or (b) a fontset and a font ligature to render the font glyph by
* using its textual name _or_ numerical character reference. Note that `material-icons` is the default fontset when
* none is specified.
* </li>
* <li> Use any of the following templates: <br/>
* <ul>
* <li>`<md-icon md-font-icon="classname"></md-icon>`</li>
* <li>`<md-icon md-font-set="font library classname or alias">textual_name</md-icon>`</li>
* <li>`<md-icon> numerical_character_reference </md-icon>`</li>
* <li>`<md-icon ng_bind="'textual_name'"></md-icon>`</li>
* <li>`<md-icon ng-bind="scopeVariable"></md-icon>`</li>
* </ul>
* </li>
* </ol>
*
* Full details for these steps can be found in the
* <a href="http://google.github.io/material-design-icons/#icon-font-for-the-web" target="_blank">
* Material Design Icon font for the web docs</a>.
*
* You can browse and search the Material Design icon style <code>.material-icons</code>
* in the <a href="https://material.io/tools/icons/" target="_blank">Material Design Icons tool</a>.
*
* ### SVG
* For SVGs, the problem with using `<img>` or a CSS `background-image` is that you can't take
* advantage of some SVG features, such as styling specific parts of the icon with CSS or SVG
* animation.
*
* `md-icon` makes it easier to use SVG icons by *inlining* the SVG into an `<svg>` element in the
* document. The most straightforward way of referencing an SVG icon is via URL, just like a
* traditional `<img>`. `$mdIconProvider`, as a convenience, lets you _name_ an icon so you can
* reference it by name instead of URL throughout your templates.
*
* Additionally, you may not want to make separate HTTP requests for every icon, so you can bundle
* your SVG icons together and pre-load them with `$mdIconProvider` as an icon set. An icon set can
* also be given a name, which acts as a namespace for individual icons, so you can reference them
* like `"social:cake"`.
*
* When using SVGs, both external SVGs (via URLs) or sets of SVGs (from icon sets) can be
* easily loaded and used.
*
* ### Localization
*
* Because an `md-icon` element's text content is not intended to be translated, it is recommended
* to declare the text content for an `md-icon` element in its start tag. Instead of using the HTML
* text content, consider using `ng-bind` with a scope variable or literal string.
*
* Examples:
*
* <ul>
* <li>`<md-icon ng-bind="myIconVariable"></md-icon>`</li>
* <li>`<md-icon ng-bind="'menu'"></md-icon>`
* </ul>
*
* <h2 id="material_design_icons">Material Design Icons tool</h2>
* Using the Material Design Icons tool, developers can easily and quickly search for a specific
* open source Material Design icon. The search is in the top left. Below search, you can select
* from the new icon themes or filter by icon category.
*
* <a href="https://material.io/tools/icons/" target="_blank" style="border-bottom:none;">
* <img src="https://user-images.githubusercontent.com/3506071/41942584-ef0695d0-796d-11e8-9436-44f25023a111.png"

* Click on the image above to open the
* <a href="https://material.io/tools/icons/" target="_blank">Material Design Icons tool</a>.
* </div>
*
* Click on any icon, then click on the "Selected Icon" chevron to see the slide-up
* information panel with details regarding a SVG download and information on the font-icon's
* textual name. This panel also allows you to select a black on transparent or white on transparent
* icon and to change the icon size. These settings only affect the downloaded icons.
*
* @param {string} md-font-icon String name of CSS icon associated with the font-face will be used
* to render the icon. Requires the fonts and the named CSS styles to be preloaded.
* @param {string} md-font-set CSS style name associated with the font library; which will be assigned as
* the class for the font-icon ligature. This value may also be an alias that is used to lookup the classname;
* internally use `$mdIconProvider.fontSet(<alias>)` to determine the style name.
* @param {string} md-svg-src String URL (or expression) used to load, cache, and display an
* external SVG.
* @param {string} md-svg-icon md-svg-icon String name used for lookup of the icon from the internal cache;
* interpolated strings or expressions may also be used. Specific set names can be used with
* the syntax `<set name>:<icon name>`.<br/><br/>
* To use icon sets, developers are required to pre-register the sets using the `$mdIconProvider` service.
* @param {string=} aria-label Labels icon for accessibility. If an empty string is provided, icon
* will be hidden from accessibility layer with `aria-hidden="true"`. If there's no aria-label on the icon
* nor a label on the parent element, a warning will be logged to the console.
* @param {string=} alt Labels icon for accessibility. If an empty string is provided, icon
* will be hidden from accessibility layer with `aria-hidden="true"`. If there's no alt on the icon
* nor a label on the parent element, a warning will be logged to the console.
*
* @usage
* When using SVGs:
* <hljs lang="html">
*
*<!-- Icon ID; may contain optional icon set prefix.
* Icons must be registered using $mdIconProvider. -->
*<md-icon md-svg-icon="social:android" aria-label="android " ></md-icon>

* </hljs>
*
* Use the <code>$mdIconProvider</code> to configure your application with
* SVG icon sets.
*
* <hljs lang="js">
* angular.module('appSvgIconSets', ['ngMaterial'])
* .controller('DemoCtrl', function($scope) {})
* .config(function($mdIconProvider) {

*
* <md-icon md-font-icon="android" aria-label="android" ></md-icon>
* <md-icon class="icon_home" aria-label="Home"></md-icon>
*
* </hljs>
*
* When using Material Font Icons with ligatures:
* <hljs lang="html">
* <!--
* For Material Design Icons
* The class '.material-icons' is auto-added if a style has NOT been specified
* since `material-icons` is the default fontset. So your markup:
* -->
* <md-icon> face </md-icon>
* <!-- becomes this at runtime: -->
* <md-icon md-font-set="material-icons"> face </md-icon>
* <!-- If the fontset does not support ligature names, then we need to use the ligature unicode.-->
* <md-icon> &#xE87C; </md-icon>
* <!-- The class '.material-icons' must be manually added if other styles are also specified-->
* <md-icon class="material-icons md-light md-48"> face </md-icon>

* `$mdIconProvider` is used only to register icon IDs with URLs. These configuration features allow
* icons and icon sets to be pre-registered and associated with source URLs **before** the `<md-icon />`
* directives are compiled.
*
* If using font-icons, the developer is responsible for loading the fonts.
*
* If using SVGs, loading of the actual svg files are deferred to on-demand requests and are loaded
* internally by the `$mdIcon` service using the `$templateRequest` service. When an SVG is
* requested by name/ID, the `$mdIcon` service searches its registry for the associated source URL;
* that URL is used to on-demand load and parse the SVG dynamically.
*
* The `$templateRequest` service expects the icons source to be loaded over trusted URLs.<br/>
* This means, when loading icons from an external URL, you have to trust the URL in the `$sceDelegateProvider`.
*
* <hljs lang="js">
* app.config(function($sceDelegateProvider) {

* '**'
* ]);
* });

*
* **Notice:** Most font-icons libraries do not support ligatures (for example `fontawesome`).<br/>
* In such cases you are not able to use the icon's ligature name - Like so:
*
* <hljs lang="html">
* <md-icon md-font-set="fa">fa-bell</md-icon>
* </hljs>
*
* You should instead use the given unicode, instead of the ligature name.
*
* <p ng-hide="true"> ##// Notice we can't use a hljs element here, because the characters will be escaped.</p>
* ```html
* <md-icon md-font-set="fa">&#xf0f3</md-icon>

* @description
* The `$mdIcon` service is a function used to lookup SVG icons.
*
* @param {string} id Query value for a unique Id or URL. If the argument is a URL, then the service will retrieve the icon element
* from its internal cache or load the icon and cache it first. If the value is not a URL-type string, then an ID lookup is
* performed. The Id may be a unique icon ID or may include an iconSet ID prefix.
*
* For the **id** query to work properly, this means that all id-to-URL mappings must have been previously configured
* using the `$mdIconProvider`.
*
* @returns {angular.$q.Promise} A promise that gets resolved to a clone of the initial SVG DOM element; which was
* created from the SVG markup in the SVG data file. If an error occurs (e.g. the icon cannot be found) the promise
* will get rejected.
*
* @usage
* <hljs lang="js">
