  /** \class Intrepid2::CubaturePolylib
      \brief Utilizes cubature (integration) rules contained in the library Polylib
      (Spencer Sherwin, Aeronautics, Imperial College London) within Intrepid.

      They are based on zeros of Jacobi polynomials,
      e.g. Legendre (alpha=beta=0, default), Chebyshev (alpha=beta=-0.5), etc.
      They are given on the interval [-1,1] and are optimal with respect to
      the following requirements, yielding 4 subclasses:
      \li Gauss             - no restrictions (all integration points are contained in the open interval (-1,1))
      \li Gauss-Radau-Left  - left-most integration point is fixed at -1
      \li Gauss-Radau-Right - right-most integration point is fixed at +1
      \li Gauss-Lobatto     - left-most and right-most integration points are fixed at -1 and +1, respectively
