Add color atoms to the passed in molecule. Note that this is not
normally required as both OEColorOverlap and OEBestOverlay make
internal copies of molecules and add color atoms automatically, but if
you continually re-use the same molecule, this can be an optimization.
Additionally, setting setCachedSelfColor to true will pre-calculate
and cache the self color on the molecule. This cached value will then
be used by OEColorOverlap and OEBestOverlay. The value can be
