/**
 * A Base <code>INotifier</code> implementation.
 * 
 * <P>
 * <code>MacroCommand, Command, Mediator</code> and <code>Proxy</code> 
 * all have a need to send <code>Notifications</code>. <P>
 * <P>
 * The <code>INotifier</code> interface provides a common method called
 * <code>sendNotification</code> that relieves implementation code of 
 * the necessity to actually construct <code>Notifications</code>.</P>
 * 
 * <P>
 * The <code>Notifier</code> class, which all of the above mentioned classes
 * extend, provides an initialized reference to the <code>Facade</code>
 * Singleton, which is required for the convienience method
 * for sending <code>Notifications</code>, but also eases implementation as these
 * classes have frequent <code>Facade</code> interactions and usually require
 * access to the facade anyway.</P>
