  The reference implementation completes with KErrNotSupported since there isn't a Cooperating System on HRP/Techview.
  On a device, State Adaptation Plug-in would request for notification from the Cooperating System for 'aEvent'.
  
  The above mentioned implementation is modified to facilitate testing and increase the code coverage of the Adaptation 
  server code.The modified functionality is as follows.
  
  
  Instead of completing the notification request with KErrNotSupported the it is passed to 
  CStateAdaptationRefEventHandler which is an active object wiht lower priority compared to 
  the server active object.Because of this a delay will be introduced in completing the notification
  request so that other active objects can run avoiding infinite loop and starvation of other 
  active objects,which will be the case if the notification request is immediately completed.
  This is strictly for testing purposes.On a device this call will be replaced by a notification request
  to cooperative system.
