deferred class TShape from TopoDS inherits TShared from MMgt

	---Purpose: A TShape  is a topological  structure describing a
	--          set of points in a 2D or 3D space.
	--          
	--          TShapes are   defined   by  their  optional domain
	--          (geometry)  and  their  components  (other TShapes
	--          with  Locations and Orientations).  The components
	--          are stored in a List of Shapes.
	--          
	--          A   TShape contains  the   following boolean flags :
	--          
	--           - Free       : Free or Frozen.
	--           - Modified   : Has been modified.
	--           - Checked    : Has been checked.
	--           - Orientable : Can be oriented.
	--           - Closed     : Is closed.
	--           - Infinite   : Is infinite.
	--           - Convex     : Is convex.
	--       
	--          
    	--          Users have no direct access to the classes derived
    	--          from TShape.  They  handle them with   the classes
    	--          derived from Shape.
