* 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.
