A, that makes sense. I have done simple inversion, but its looking
like i may need a few iterations still.

Also, btw, though I should tell you. I have noticed a bit of a problem
with bonded potentials produced by csg_botzmann. I have a simple
molecule that is put into End-Ceter-Center-End bids. I have used
csg_boltzmann to do inversion and also did it by hand myself to
compare. Center-Center bonds are perfect, but End-Center ones are not
right. I haven't yet figured out why.
