In particular, notice that I am using Hartree atomic units for energies, but SI (or any units actually) for the wavefunction. So the wave function contains the bohr radius "a", while the energies only contain the Z. I also need speed of light for the dirac energies. Should we use (Hartree) atomic units, or SI units? We should use one sets of units for everything. I think we should implement this units independent, and use symbols like "c", "a", "Z", and then also allow some simplified version that gives you the energies in atomic units, as that's what is used most often.
