      Given a desired number of points N, the best choice for abscissas is
      a set of Lebesgue points, which minimize the Lebesgue constant,
      which describes the error in polynomial interpolation.  Sets of
      Lebesgue points are difficult to define mathematically.  Fekete
      points are a related, computable set, defined as those sets maximizing
      the magnitude of the determinant of the Vander
