/**
 * Basic button component.
 *
 * Default button size is `medium` and status color is `primary`:
 * @stacked-example(Button Showcase, button/button-showcase.component)
 *
 * ```html
 * <button nbButton></button>
 * ```
 * ### Installation
 *
 * Import `NbButtonModule` to your feature module.
 * ```ts
 * @NgModule({
 *   imports: [
 *   	// ...
 *     NbButtonModule,
 *   ],
 * })
 * export class PageModule { }
 * ```
 * ### Usage
 *
 * Buttons are available in multiple colors using `status` property:
 * @stacked-example(Button Colors, button/button-colors.component.html)
 *
 * There are three button sizes:
 *
 * @stacked-example(Button Sizes, button/button-sizes.component.html)
 *
 * And two additional style types - `outline`:
 *
 * @stacked-example(Outline Buttons, button/button-outline.component.html)
 *
 * and `hero`:
 *
 * @stacked-example(Button Colors, button/button-hero.component.html)
 *
 * Buttons available in different shapes, which could be combined with the other properties:
 * @stacked-example(Button Shapes, button/button-shapes.component)
 *
 * `nbButton` could be applied to the following selectors - `button`, `input[type="button"]`, `input[type="submit"]`
 * and `a`:
 * @stacked-example(Button Elements, button/button-types.component.html)
 *
 * Button can be made `fullWidth`:
 * @stacked-example(Full Width Button, button/button-full-width.component.html)
 *
