[phenixbb] selective nonbonded restraint removal

You could model this with alternative conformations. If you assign
"altloc" A and B to two conformers of your protein, and just, say, B
to your TAM, then the ligand would only "see" your B protein. If you
don't define the B conformer (no atoms) then TAM wouldn't see that
part of the protein at all.
Actually, this approach seems better to me than working with
atom selections.
