deferred class BoundedCurve from Geom inherits Curve from Geom


    	---Purpose : The abstract class BoundedCurve describes the
    	-- common behavior of bounded curves in 3D space. A
    	-- bounded curve is limited by two finite values of the
    	-- parameter, termed respectively "first parameter" and
    	-- "last parameter". The "first parameter" gives the "start
    	-- point" of the bounded curve, and the "last parameter"
    	-- gives the "end point" of the bounded curve.
    	-- The length of a bounded curve is finite.
    	-- The Geom package provides three concrete classes of bounded curves:
    	-- - two frequently used mathematical formulations of complex curves:
    	--   - Geom_BezierCurve,
    	--   - Geom_BSplineCurve, and
    	-- - Geom_TrimmedCurve to trim a curve, i.e. to only
    	--   take part of the curve limited by two values of the
    	--   parameter of the basis curve.
