This patch adds the PALP normal form algorithm natively into the
`lattice_polytope` class, as well as a modified algorithm that is more
efficient for some polytopes. This is then also used directly to calculate
a normal form for Laurent polynomials.
These algorithms require abilities to permute rows and columns of
matrices, as well as find automorphisms of matrices under these
operations, and lattice polytopes under GL(n,Z) transformations. These are
also implemented here.
