  //! Constructs a boundary object defined by the 3d curve CurveOnSurf.
  //! The surface to be filled along this boundary will be in the
  //! tolerance range defined by Tol3d.
  //! What's more, at each point of CurveOnSurf, the angle
  //! between the normal to the surface to be filled along this
  //! boundary, and the normal to the surface on which
  //! CurveOnSurf lies, must not be greater than TolAng.
  //! This object is to be used as a boundary for a
  //! GeomFill_ConstrainedFilling framework.
  //! Warning
  //! CurveOnSurf is an adapted curve, that is, an object
  //! which is an interface between:
  //! -   the services provided by a curve lying on a surface from the package Geom
  //! -   and those required of the curve by the computation algorithm which uses it.
  //! The adapted curve is created in the following way:
  //! Handle(Geom_Surface) mySurface = ... ;
  //! Handle(Geom2d_Curve) myParamCurve = ... ;
  //! // where myParamCurve is a 2D curve in the parametric space of the surface mySurface
  //! Handle(GeomAdaptor_HSurface)
  //! Surface = new
  //! GeomAdaptor_HSurface(mySurface);
  //! Handle(Geom2dAdaptor_HCurve)
  //! ParamCurve = new
  //! Geom2dAdaptor_HCurve(myParamCurve);
  //! CurveOnSurf = Adaptor3d_CurveOnSurface(ParamCurve,Surface);
  //! The boundary is then constructed with the CurveOnSurf object:
  //! Standard_Real Tol = ... ;
  //! Standard_Real TolAng = ... ;
  //! myBoundary =  GeomFill_BoundWithSurf (
  //! CurveOnSurf, Tol, TolAng );
