Merge pull request #2899 from CyrusBiotechnology/for_commons/indigo/nmer_refactor
From @indigogo at Cyrus.
* new unit test for core/scoring/methods/NMerSVMEnergy, the scoring method used for tcell epitope prediction. unit test just compares epitope predictions for rosetta's idealized trpcage pose
* refactoring of all 3 tcell epitope scoring terms (NMerSVMEnergy,NMerPSSMEnergy,NMerRefEnergy). no functional changes, just added full constructors like I should have done in the first place, also some new functions to extract model energies before everything is summed/averaged into total residue energy
