 * Deprecated with v2.0, will be removed in v3.0
 * Using a modal in your application requires *this* component (`n-modal-placeholder`).
 * It would generally be placed near the end of your app component template
 * (app.component.ts or app.component.html) as:
 *
 * ```html
 * ...
 * <ibm-modal-placeholder></ibm-modal-placeholder>
 * ```
 *
 * A more complete example for `Modal` is given as follows:
 *
 * ```html
 * <ibm-modal size="xl" (overlaySelected)="closeModal()">
 * 	<ibm-modal-header (closeSelect)="closeModal()">Header text</ibm-modal-header>
 * 	<section class="modal-body">
 * 		<h1>It Works!</h1>
 * 		{{modalText}}
 * 	</section>
 * 	<ibm-modal-footer><button class="btn cancel-button" (click)="closeModal()">Cancel</button></ibm-modal-footer>
 * </ibm-modal>
 * ...
 * <ibm-modal-placeholder></ibm-modal-placeholder>
 * ```
