-%% Implementation of create,config,read,destroy
-%% Comment: In the gstk process there is not concept call 'name', only
-%%          pure oids. Names are stripped of by 'gs' and this simplifies
-%%          gstk a lot.
-%% Comment: For performance reasons gstk.erl ans gs.erl communicats through
-%%          tuples. This is unfortunate but we don't want to pack the same
-%%          thing too many times.
-%% Pre (for all functions): GS guarantees that the object (and parent if
-%%          necessary) exists.
