/**
 * Control event listeners with an observable operator without triggering change detection
 * every time the event fires
 *
 * Usage:
 * <button (observe.throttleTime-500.click)="foo()"></button>
 *
 * The method used must be present on the Observable object
 * e.g. through an explicit import:
 * import 'rxjs/add/operator/throttleTime';
 *
 *
 * To get finer-grained control and the possibility to add multiple observable operators
 * use the ObserveEventDirective.
