    /*!
   A Kochanek-Bartels spline can be used to
   interpolate a sequence of points
   p = (p1, p2, ...) excluding the first point.
   The curve can modified by choosing different
   parameters for 'tension', 'bias' and
   'continuity'. Sometimes these curves are
   also called TCB-splines. A segment of
   this curve is a special case of a cubic
   Hermite curve, see cubicHermite().
