Merge pull request #3325 from RosettaCommons/vmullig/update_his_p
Tweaking HIS_P.params to allow confirmational sampling and peptide structure prediction at low pH
Adding Ramachandran information. At some point, we really should make the protonated variants into patches instead of separate params files. For now, this is a very minor tweak.
Update: I'll update all of the protonation params files while I'm at it.
This was an old pull request approved some time ago, so I re-tested it (with the latest master merged into the branch) before merging it into master.
