Detailed Description

TODO: De-duplicate shared code from RotateJumpAxisMover (angle picking code)

This mover rotates a specific AtomTree Torsion degree of freedom (any valid 4-body torsion). It can rotate by a fixed amount, within a range, or randomly. Optionally, the mover will attempt to internally score the move with MMTorsionEnergy (similar to check_rama in Small/ShearMover). The mover will print a warning message at apply time if the specified DOF is bad. For now this mover only allows one DOF; if you want to have it consider multiple DOF's that might be a good idea. The DOF is determined by a set of 4 atoms; this allows the mover to check the validity of the DOF. I found it conceptually simpler to think about the 4 atoms involved in the torsion than try to trace DOF_IDs.

calculate mmt score for the moving bond This is the stupidest possible method - score the whole pose.
