Functions for computing the Dubiner basis functions in DG methods.

This file contains functionality for computing the basis functions and relating coordinates transformation functions used in discontinuous Galerkin methods for variaous orders of numerical representation. The basis functions chosen for the DG method are the Dubiner basis, which are Legendre polynomials modified for tetrahedra, which are defined only on the reference/master tetrahedron.
