* Description:  CNssVASDBMgr is the starting point to begin interaction with VAS. 

*               The client must first create and Initialize the CNssVASDBMgr; then 

*               request the ContextMgr, TagMgr, VASDBEventNotifier, or 

*               TagSelectNotifier to begin using VAS services.
