/**
* Use by directives and components to emit custom Events.
*
* ### Examples
*
* In the following example, `Zippy` alternatively emits `open` and `close` events when its
* title gets clicked:
*
* ```
* @Component({
* selector: 'zippy',
* template: `
* <div class="zippy">
* <div (click)="toggle()">Toggle</div>
* <div [hidden]="!visible">
* <ng-content></ng-content>
* </div>
* </div>`})
* export class Zippy {
* visible: boolean = true;
* @Output() open: EventEmitter<any> = new EventEmitter();
* @Output() close: EventEmitter<any> = new EventEmitter();
*
* toggle() {
* this.visible = !this.visible;
* if (this.visible) {
* this.open.emit(null);
* } else {
* this.close.emit(null);
* }
* }
* }
* ```
*
* The events payload can be accessed by the parameter `$event` on the components output event
* handler:
*
* ```
* <zippy (open)="onOpen($event)" (close)="onClose($event)"></zippy>
* ```
*
* Uses Rx.Observable but provides an adapter to make it work as specified here:
* https://github.com/jhusain/observable-spec
*
* Once a reference implementation of the spec is available, switch to it.
* @stable
