*
* @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 consider 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.
*
* ### 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.When use font-icons, developers must following 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) font ligatures to render the font glyph by using its textual name</li>
* <li> Use <md-icon md-font-icon="classname" /> or <br/>
* use <md-icon md-font-set="font library classname or alias"> textual_name </md-icon> or <br/>
* use <md-icon md-font-set="font library classname or alias"> numerical_character_reference </md-icon>
* </li>
* </ol>
*
* Full details for these steps can be found:
*
* <ul>
* <li>http://google.github.io/material-design-icons/</li>
* <li>http://google.github.io/material-design-icons/#icon-font-for-the-web</li>
* </ul>
*
* The Material Design icon style <code>.material-icons</code> and the icon font references are published in
* Material Design Icons:

* Using the Material Design Icon-Selector, developers can easily and quickly search for a Material Design font-icon and

*
* @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.
