/**

 CSimAdaptationRefEventHandler acts as a dummy event notifier in the absence of Cooperating system

  *********Need for the class*********

  On a device when NotifySimEvent is called, Sim Adaptation Plug-in would request for notification 

  from the Cooperating System for 'aEvent'.

  But this implementation will cause problems in the following scenario.

  *********Problem*********

  This API is used by Adaptation server to service the clients which request for notifications .

  This is done as follows.

  Adaptation server always tracks the events by calling NotifySimEvent during the whole life time 

  of the server.It first calls this API in the startup of the server and subsequently whenever an event 

  is notified(by completing the call NotifySimEvent) adaptation server resubmits the request 

  by calling NotifySimEvent .

  In this context if NotifySimEvent just completes the message immediately this results in a infinite 

  loop and starves other active objects with same priority.

  *********Solution*********

  To solve this problem NotifySimEvent will forward the notification request from adaptation server 

  to the test active object(CSimAdaptationRefEventHandler) which has lesser priority compared to 

  adaptation servers active object.

  In the RunL() method of this test active object the notification request is completed.  

  This will delay the completion of notification message till all the servers active objects 

  which have higher priority are run.
