Detailed Description

Class definition of a functor that interpolates data points to compute knots and control points for a cubic BSpline.

Based on section 9.3.4 of "The NURBS book", "PIEGL, L. and TILLER, W.", Springer, 1997.

This could be used as a HxBSplineCurve constructor, but that would require a more general version.
