/**
 * Modal service is used to to create modal dialogs. It creates modal dialogs dynamically.
 * The service also keeps track of the created modal dialog and can close it by calling the
 * service's close()
 *
 * Modal service requires a ViewContainer to insert newly created modals. This is taken care
 * by the ModalComponent.
 *
 * Usage:
 *     Add   <aw-modal></aw-modal>  into your application main html. It needs to be on every
 *     page where a modal dialog will appear.
 *
 *    1.  Popup a dialog without creating your own component.
 *        Use the existing DialogComponent in widgets.
 *
 *             this.modalService.open<DialogComponent>(DialogComponent, {
 *                     title: 'My Popup Title',
 *                     body: 'My Popup Body'
 *              });
 *
 *
 *   2.   Creating your own Dialog Component to popup.
 *
 *         let componentRef = this.modalService.open<MyDialogComponent>(MyDialogComponent,
 * {inputs});
 *
 *          @Component({
 *                selector: 'aw-mydialog' ,
 *                           template: `
 *                                         <aw-dialog (onClose)="closePopup()">
 *                                              <ng-template #titleTemplate>
 *                                                 <span><i class="fa fa-envira" ></i>This is my
 *     Title </span>
 *                                              </ng-template>
 *                                              <ng-template #bodyTemplate>
 *                                                 <span><i class="fa fa-envira" ></i>This is my
 *     Body </span>
 *                                              </ng-template>
 *                                        </aw-dialog>
 *                                     `
 *         })
 *         export class MyDialogComponent extends DialogComponent implements OnInit {
 *                     constructor(private modalService: ModalService) {

 *                       }
 *                     ngOnInit() { }
 *
