 *
 *	Abstract:
 *		Instances of this class represent the application registry for a 
 *		single conference.  This is a dual purpose class that is designed 
 *		to support both a Top Provider node and all other nodes.  The 
 *		information base for the application registry is completely contained at 
 *		the Top Provider node. This information is not distributively held at 
 *		all nodes in the conference like roster information.  It is completely 
 *		managed at the Top Provider.  Therefore all requests to alter 
 *		information in the registry or get information from the registry are 
 *		made to the Top Provider.
 *
 *		When an Application Registry object is instantiated it is informed if it 
 *		is the Top Provider or not.  Application Registry objects that are Top 
 *		Providers are responsible for maintaining the registry information base 
 *		for the entire conference.  It is also responsible for servicing all 
 *		incoming requests and sending out the necessary confirms.  Application 
 *		Registry objects that are not Top Providers are responsible for sending 
 *		all requests to the Top Provider node.  They are also responsible for 
 *		issuing confirms to the CAppSap that made the request after receiving the 
 *		responses back from the Top Provider registry.  All Application Registry 
 *		requests include an Entity ID associated with the APE that made the 
 *		request.  Note that all registry requests are processed in the order 
 *		that they are received.  Therefore, there is no need to include 
 *		sequencing data with each request.  
 *
 *	Caveats:
 *		None.
