Merge pull request #1569 from RosettaCommons/everyday847/handle_insertions_pdbinfo
Unit test added--note that I'm setting up the unit test so that it tests only the unit I'm interested in, i.e., how this function works on the PDBInfo. So I'm setting up a PDBInfo with the exact defect I want to repair and then repairing it. Actually inserting a residue via a call from Conformation, then repairing the result, would be an integration test!
