/**
* A base <code>IObserver</code> implementation.

* <P>
* An <code>Observer</code> is an object that encapsulates information
* about an interested object with a method that should
* be called when a particular <code>INotification</code> is broadcast. </P>
*
* <P>
* In PureMVC, the <code>Observer</code> class assumes these responsibilities:
* <UL>
* <LI>Encapsulate the notification (callback) method of the interested object.</LI>
* <LI>Encapsulate the notification context (this) of the interested object.</LI>
* <LI>Provide methods for setting the notification method and context.</LI>
* <LI>Provide a method for notifying the interested object.</LI>
