void notifyShutdown( string regName )
This method must be called by a tool or manager just prior to locally initiated shutdown, i.e. shut down initiated by the user via the client GUI, or by logic internal to the client. The tool or manager identifies itself to the SDM via the argument regName, which must contain the client's complete registry name.
Note: the client must not call this method, if it is shutting down due to receiving the exitApp message from the SDM.
