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.
