Class Observer

          object --+    
                   |    
interfaces.IObserver --+
                       |
                      Observer

A base IObserver implementation.

An Observer is an object that encapsulates information about an interested object with a method that should be called when a particular INotification is broadcast.

In PureMVC, the Observer class assumes these responsibilities:

Encapsulate the notification (callback) method of the interested object.

Encapsulate the notification context (this) of the interested object.

Provide methods for setting the notification method and context.

Provide a method for notifying the interested object.
