+ * @description
+ * The `<md-icon>` directive is an markup element useful for showing an icon based on a font-icon
+ * or a SVG. Icons are 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.
+ *
+ * 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:
+ *
+ * <ul>

+ * <li>https://www.google.com/design/icons/#ic_accessibility</li>

+ * <h2 id="material_design_icons">Material Design Icons</h2>
+ * Using the Material Design Icon-Selector, developers can easily and quickly search for a Material Design font-icon and
+ * determine its textual name and character reference code. Click on any icon to see the slide-up information
+ * panel with details regarding a SVG download or information on the font-icon usage.

+ * @param {string} md-font-icon 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 `$mdIconProvider.fontSet(<alias>)` to determine the style name.
+ * @param {string} md-svg-src URL [or expression ] used to load, cache, and display an external SVG.
+ * @param {string} md-svg-icon Name used for lookup of the icon from the internal cache; interpolated strings or
+ * expressions may also be used. Specific set names can be used with the syntax `<set name>:<icon name>`.<br/><br/>
+ * To use icon sets, developers are required to pre-register the sets using the `$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.
