deferred class HCurve from Adaptor3d inherits TShared from MMgt
---Purpose: Root class for 3D curves manipulated by handles, on
-- which geometric algorithms work.
-- An adapted curve is an interface between the
-- services provided by a curve and those required of
-- the curve by algorithms which use it.
-- Two derived concrete classes are provided:
-- - GeomAdaptor_HCurve for a curve from the Geom package
-- - Adaptor3d_HCurveOnSurface for a curve lying
-- on a surface from the Geom package.
