deferred class MakeShape from BRepBuilderAPI inherits Command from BRepBuilderAPI

	---Purpose: This    is  the  root     class for     all  shape
	--          constructions.  It stores the result.
	--          
	--          It  provides deferred methods to trace the history
	--          of sub-shapes.
