Exploits translation invariance in construction of Jellium hamiltonian in dual basis, which also impacts construction of any chemical / material system in the dual basis. Speedup is roughly a factor of N in the size of the basis.

Could probably get further speedups by making routines which create the diagonal hamiltonian matrices directly instead of building fermion operators.
