/**
 * Icon component. Allows to render both `svg` and `font` icons.
 * Starting from Nebular 4.0 uses [Eva Icons](https://akveo.github.io/eva-icons/) pack by default.
 *
 * Basic icon example:
 * @stacked-example(Showcase, icon/icon-showcase.component)
 *
 * Icon configuration:
 *
 * ```html
 * <nb-icon icon="star"></nb-icon>
 * ```
 * ### Installation
 *
 * By default Nebular comes without any pre-installed icon pack.
 * Starting with Nebular 4.0.0 we ship separate package called `@nebular/eva-icons`
 * which integrates SVG [Eva Icons](https://akveo.github.io/eva-icons/) pack to Nebular. To add it to your
 * project run:
 * ```sh
 * npm i @nebular/eva-icons@next
 * ```
 * This command will install Eva Icons pack. Then register `NbEvaIconsModule` into your app module:
 * ```ts
 * import { NbEvaIconsModule } from '@nebular/eva-icons';
 *
 * @NgModule({
 *   imports: [
 *     // ...
 *     NbEvaIconsModule,
 *   ],
 * })
 * export class AppModule { }
 * ```
 * Last thing, import `NbIconModule` to your feature module where you need to show an icon:
 * ```ts
 * import { NbIconModule } from '@nebular/theme';
 *
 * @NgModule({
 *   imports: [
 *     // ...
 *     NbIconModule,
 *   ],
 * })
 * export class PageModule { }
 * ```
 * ### Usage
 *
 * Icon can be colored using `status` input:
 * ```html
 * <nb-icon icon="star" status="warning"></nb-icon>
 * ```
 *
 * Colored icons:
 * @stacked-example(Colored Icons, icon/icon-colors.component)
 *
 * In case you need to specify an icon from a specific icon pack, this could be done using `pack` input property:
 * ```html
 * <nb-icon icon="star" pack="font-awesome"></nb-icon>
 * ```
 * Additional icon settings (if available by the icon pack) could be passed using `options` input:
 *
 * ```html
 * <nb-icon icon="star" [options]="{ animation: { type: 'zoom' } }"></nb-icon>
 * ```
 *
 * @styles
 *
 * icon-font-size:
 * icon-line-height:
 * icon-width:
 * icon-height:
 * icon-primary-color:
 * icon-info-color:
 * icon-success-color:
 * icon-warning-color:
 * icon-danger-color:
