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.
