deferred class TShape from PTopoDS inherits Persistent from Standard

	---Purpose: A TShape  is a topological  structure describing a
	--          set of points in a 2D or 3D space.
	--          

    	--  All the information stored are potentially frozen.  So has
    	--  the "free"  information no  sense in  the D.B. context.  A
    	--  Shape from PTopoDS translated in  a Shape from TopoDS will
    	--  be automatically frozen (not free).
