Brute force potential-calculation works, as well as lattice generation from lattice vectors and such
latest updates to potential branch - but now going to switch development to another method
First iteration of building the hamiltonian matrix at an arbitrary wavevector - still entirely undebugged
Fake band structures work! Midway through writing the discrete convolve, hope it's not too slow.
Generate a set of vectors in an arbitrary first Brillouin zone, and implement the stupid iteration
Get the central equation solver as good as it'll get for now (not that great)
