 *
 *	Abstract:
 *		This module manages the creation and deletion of various objects
 *		within GCC.  This includes the Control SAP, the Application SAPs, the
 *		Conference objectis indexed by the Conference ID.  Primitives are
 *		routed to the as and the MCS interface.  Conferences are maintained
 *		in a list that ppropriate conference object based on the Conference ID.
 *		The controller module is also responsible for routing Connect Provider 
 *		indications to the appropriate destination.
 *
 *		SEE THE INTERFACE FILE FOR A MORE DETAILED EXPLANATION OF THIS CLASS
 *
 *	Portable:
 *		Not Completely
 *
 *	Protected Instance Variables:
 *		None.
 *
 *	Private Instance Variables:
 *		g_pMCSIntf  				-	Pointer to the MCS Interface object.
 *										All request to MCS and all callbacks
 *										received from MCS travel through this
 *										interface.
 *		m_ConfList2 				-	This list maintains the active 
 *										conference objects.
 *		m_ConfPollList      		-	The conference poll list is used when
 *										polling the conference objects.  A
 *										seperate poll list is needed from the
 *										conference list to avoid any changes
 *										to the rogue wave list while it is
 *										being iterated on.
 *		m_AppSapList           		-	This list maintains all the registered
 *										application SAP objects.
 *		m_PendingCreateConfList2	-	This list is used to maintain
 *										conference information for pending
 *										conference objects that have not
 *										yet been created (i.e. CreateRequest
 *										has been received but not the Create
 *										Response).
 *		m_PendingJoinConfList2		-	This list is used to maintain  the
 *										join information for pending
 *										conference joins that have not
 *										yet been accepted (i.e. JoinRequest
 *										has been received but not the Join
 *										Response).
 *		m_ConfDeleteList    		-	This list contains any conference 
 *										objects that have been marked for
 *										deletion.  Once a conference object is
 *										put into this list on the next call to
 *										PollCommDevices it will be deleted.
 *		m_fConfListChangePending    	This flag is used to inform when the
 *										m_ConfList2 changes.  This includes
 *										when items are added as well as deleted.
 *		m_ConfIDCounter     		-	This instance variable is used to
 *										generate Conference IDs.
 *		m_QueryIDCounter			-	This instance variable is used to 
 *										generate the DomainSelector used in the
 *										query request.
 *		m_PendingQueryConfList2 	-	This list contains the query id (used
 *										for the domain selector in the query
 *										request).  This query id needs to be
 *										kept around so that the domain selector
 *										can be deleted when the query response
 *										comes back in (or if the controller is
 *										deleted before the confirm comes back).
 *
 *
 *	WIN32 related instance variables:
 *
 *		g_hevGCCOutgoingPDU			-	This is a Windows handle to an event
 *										object that signals a GCC PDU being 
 *										queued and ready to send on to MCS.
 *
 *	WIN16 related instance variables:
 *
 *		Timer_Procedure				-	This is the Process Instance of the
 *										timer procedure used in the Win16
 *										environment to get an internal 
 *										heartbeat.
 *		Timer_ID					-	This is the timer id of the timer that
 *										may be allocated in the Win16 
 *										constructor.
 *
 *	Caveats:		
 *		None.
