NotificationCenter

==================

NotificationCenter handles messages and distributes them to all observers.

How to use

----------

NotificationCenter facilitates communications between classes or plugins that do not know about each other.

When a class posts a notification, all observers are notified. The object posting the notification does not need to know anything about the observers.

	var MyTabController = new Class({

		// Tab controller code here

		activateTab: function(tab) {

			// set styles, etc

			NotificationCenter.postNotification('TabActivated', { controller: this, tab: tab });

		}

	});

An object can add itself as an observer for a notification by passing a callback function that will be executed when another object posts that notification.

	var MyVideoPlayer = new Class({

		initialize: function() {

			// Video player code here

			NotificationCenter.addObserver('TabActivated', function(message) {

				if (message.tab.id === '#video') {

					this.restartPlayer();

				}

			})

		}

	});

An object can post notifications to all listeners using the wildcard '*'. Additionaly, an object can observe all notifications using the '*' wildcard.

	var MyBroadcaster = new Class({

		initialize: function() {

			// Notify all observers

			NotificationCenter.postNotification('*', {msg: 'Broadcaster initialized!'});

		}

	});

	

	var MySpy = new Class({

		initialize: function() {

			NotificationCenter.addObserver('*', this.logNotification.bind(this));

		},

		logNotification: function(message) {

			console.dir(message);

		}

	});
