* \class NonUniformBSpline
* \brief BSpline with nonuniform knot spacing.
*
* This class is a bspline with nonuniform knot spacing. The
* use can specify a set of points and a set of knots and the
* spline will attempt to find the control points which will
* cause the spline to interpolate the points.
*
* CAUTION: THIS CLASS IS STILL UNDER DEVELOPMENT.
