      This software is primarily intended as an illustration of the problems
      that can occur when the interpolation problem is naively formulated
      using the Vandermonde matrix.  If the underlying interpolating basis
      is the usual family of monomials, then the Vandermonde matrix will 
      very quickly become ill-conditioned for almost any set of nodes.

      If the nodes can be selected, this can provide a small amount of
