deferred class HSurface from Adaptor3d 

inherits TShared from MMgt

	---Purpose: Root class for surfaces manipulated by handles, on
    	-- which geometric algorithms work.
    	-- An adapted surface is an interface between the
    	-- services provided by a surface and those required of
    	-- the surface by algorithms which use it.
    	-- A derived concrete class is provided:
    	-- GeomAdaptor_HSurface for a surface from the Geom package.
