 *  CExampleAllowance Class
 *
 *  This class inherits the minimum number of interfaces required to create
 *  an RMA Allowance plug-in. The IRMAPlayerConnectionAdviseSink interface 
 *  provides notifications about significant events in a connected player's
 *  lifetime. The IRMAPlugin interface is required by all plug-ins to handle 
 *  fundamental plug-in operations. Since this is a COM object, this class 
 *  also inherits COM's IUnknown interface to handle object reference counting 
 *  and interface query.
