/**
 * Component to display an icon. It can be used in the following ways:
 *
 * - Specify the svgIcon input to load an SVG icon from a URL previously registered with the
 *   addSvgIcon, addSvgIconInNamespace, addSvgIconSet, or addSvgIconSetInNamespace methods of
 *   MatIconRegistry. If the svgIcon value contains a colon it is assumed to be in the format
 *   "[namespace]:[name]", if not the value will be the name of an icon in the default namespace.
 *   Examples:
 *     `<mat-icon svgIcon="left-arrow"></mat-icon>
 *     <mat-icon svgIcon="animals:cat"></mat-icon>`
 *
 * - Use a font ligature as an icon by putting the ligature text in the `fontIcon` attribute or the
 *   content of the `<mat-icon>` component. If you register a custom font class, don't forget to also
 *   include the special class `mat-ligature-font`. It is recommended to use the attribute alternative
 *   to prevent the ligature text to be selectable and to appear in search engine results.
 *   By default, the Material icons font is used as described at
 *   http://google.github.io/material-design-icons/#icon-font-for-the-web. You can specify an
 *   alternate font by setting the fontSet input to either the CSS class to apply to use the
 *   desired font, or to an alias previously registered with MatIconRegistry.registerFontClassAlias.
 *   Examples:
 *     `<mat-icon fontIcon="home"></mat-icon>
 *     <mat-icon>home</mat-icon>
 *     <mat-icon fontSet="myfont" fontIcon="sun"></mat-icon>
 *     <mat-icon fontSet="myfont">sun</mat-icon>`
 *
 * - Specify a font glyph to be included via CSS rules by setting the fontSet input to specify the
 *   font, and the fontIcon input to specify the icon. Typically the fontIcon will specify a
 *   CSS class which causes the glyph to be displayed via a :before selector, as in
 *   https://fontawesome-v4.github.io/examples/
 *   Example:
 *     `<mat-icon fontSet="fa" fontIcon="alarm"></mat-icon>`
