class Curve2d from BRepAdaptor inherits Curve from Geom2dAdaptor

	---Purpose: The Curve2d from BRepAdaptor allows to use an Edge
	--          on   a Face like   a  2d   curve. (curve  in   the
	--          parametric space).
	--          
	--          It  has  the methods    of the class Curve2d  from
	--          Adpator. 
	--          
	--          It  is created or  initialized with a  Face and an
	--          Edge.  The methods are  inherited from  Curve from
	--          Geom2dAdaptor.
