Creating System Utility Policy plug-in

System Utility Policy plug-ins in the SSM Utility Server are intended to monitor some property of the system. It is used by the SSM for efficient handling of a system property change.

1. 
   Define a class that implements MSsmUtility interface.
2. 
   Export the static method to create new System Utility Policy plug-in as shown in the code snippet:

   
   EXPORT_C MSsmUtility* CLafShutdownEventObserverAdaptor::NewL()
   {
       CLafShutdownEventObserverAdaptor* self = new (ELeave) CLafShutdownEventObserverAdaptor();
       return static_cast<MSsmUtility*>(self);
   }
   

   The code returns a new plug-in object for SUP plug-in.
