Merge pull request #561 from RosettaCommons/vmullig/perturb_torsion
Add a "perturb" option to the SetTorsion mover
Currently, the mover lets you set a torsion value, or randomize it completely. A "perturb" option will let the mover take an existing torsion value and add a small random value to it.
Tasks:
Fix uninitialized variables in this mover.
Update comments in this mover.
Add the perturb functionality, with support for uniform or Gaussian perturbation.
Add RosettaScripts hooks.
Add an integration test.
Update documentation.
Debug.
