* MatIconRegistry. If the svgIcon value contains a colon it is assumed to be in the format

* 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>
