* 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 content of the `<mat-icon>`
* component. 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>home</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://fortawesome.github.io/Font-Awesome/examples/
