Resolve "Spectral elements implementation"
- Will introduce a subroutine for computing Lagrange polynomials at a given set of points
- Will introduce two new shape function sets: Lagrange-HEX64 and Chebyshev-HEX64
- Accompanying modifications to kernel routines doing quadrature ops to take the spectral element into account
- Subroutine to modify a lagrangian-type mesh coming from gmsh to a chebyshev collocated one.
