Merge pull request #2408 from RosettaCommons/guffysl/set_up_metals_manually
Adds additional tools for handling metals and metal-containing ligands in Rosetta. MetalContactsConstraintGenerator adds distance, angle, and dihedral constraints between (optionally specified) contacts and a user-specified metal atom, either as a single ion or as part of a ligand. LigandMetalContactSelector identifies and selects residues that form contacts with selected metal-containing residues.
