-* Description:  MNssContextManager interface provides context processing methods for 
-*				 the client. The client  gets an instance of the context manager 
-*				 from the vas db manager. The vas db manager owns the context manager 
-*				 and is responsible for deleting the context manager. Clients should not 
-*				 directly delete the context manager. The context manager is simply a 
-*				 colllection of utility methods  that are pure virtuals. These methods are implemented
-*				 internal to VAS, and thus transparent to the client.

-*  MNssContextMgr is the public interface class for context management.
-*  It provides methods for context creation, saving context into the
-*  VAS database, retriving contexts from VAS database, and deletion of 
-*  context from the VAS database. A context manager cannot be instantiated
-*  directly but needs to be got from the VAS DB manager.
