OESetCachedSelfColor

bool OESetCachedSelfColor(OEChem::OEMCMolBase &mol,
                          const OEColorForceField &cff)
bool OESetCachedSelfColor(OEChem::OEMolBase &mol,
                          const OEColorForceField &cff)

Using the passed-in OEColorForceField, calculate and store the self color on each molecule. For the OEMCMolBase, each conformer gets its own stored value. To retrieve the value, use OEGetCachedSelfColor. OEColorOverlap and OEBestOverlay will use the cached value instead of re-calculating the self terms.
