/**
 * The `ToasterService` provides a capability to build toast notifications.
 *
 * `ToasterService.show(message, config)` accepts two params, config is optional.
 *
 * ### Import
 *
 * Import `ToasterModule` to your app module.
 * ```ts
 * @NgModule({
 *   imports: [
 *     // ...
 *     ToasterModule,
 *   ],
 * })
 * export class AppModule { }
 * ```
 *
 * ### Usage
 *
 * Calling `ToasterService.show(...)` will render new toast and return `ToasterRef` with
 * help of which you may close newly created toast by calling `close` method.
 *
 * ```ts
 * const toastRef: ToasterRef = this.toasterService.show(...);
 * toastRef.close();
 * ```
 *
 * Config accepts following options:
 *
 * `type` - coloring and icon of the toast.
 * Default is `info`.
 *
 * `duration` - the time after which the toast will be destroyed.
 * `0` means endless toast, that may be destroyed by click only.
 * Default is 3000 ms.
 *
 * `position` - determines where on the screen toast will be rendered.
 * Default is `top-end`, hardcoded for now.
 *
 * `destroyByClick` - provides a capability to destroy toast by click.
 * Default is true.
