Deferred class for a function used to compute a
blending surface between a surface and a curve, using
a guide line. This function is used to find a
solution on a done point of the curve.
The vector <X> used in Value, Values and Derivatives
methods has to be the vector of the parametric
coordinates w, U, V where w is the parameter on the
guide line, U,V are the parametric coordinates of a
point on the partner surface.
