Summary: microheterogenicity → microheterogeneity

ChimeraX simply does not handle microheterogeneity (e.g residue 782 in chain A is both a TYR and a PTR). Once the NIH3D script pull request is incorporated, the script will skip coulombic for this structure. If we wind up using Gasteiger charges (which seems likely), then coulombic will "work", though the charge concentrations will be roughly twice as high as they should be in the microheterogeneous positions.
