PolynomialArray.hs

   1 -- | The PolynomialArray module contains one type, 'PolynomialArray',
   2 --   and a smart constructor for it. The array is essentially a hash;
   3 --   the unique keys can be thought of as a cube/tetrahedron pair, and
   4 --   the associated value is the polynomial function over that
   5 --   tetrahedron. Rather than define 'Ord' instances and a proper map,
   6 --   we just use the indices i,j,k along with the tetrahedron number
   7 --   as the keys.
