Fixed a minor bug with helical bundle generation
Fixed a minor bug with helical bundle generation when the repeating unit is more than one residue. The number of mainchain atoms in the last (overhang) residue was being checked incorrectly.
Also, adding a feature to the fit_helixparams app that lets the user specify that certain bond angles or bond lengths are non-ideal.
...Aaaaand in the process I caught two more bugs in the BundleGridSampler.
