Detailed Description

Construct optical material IDs and map from a geometry material ID.

This construct a material -> optical material mapping based on whether the RINDEX table is present on a Geant4 material.

As a reminder, geometry materials correspond to G4Material and physics materials correspond to G4MaterialCutsCouple .

Todo:: Use GeantGeoParams (or an upcoming GeantModel) to translate geometry IDs: the G4Material's "index" can be offset from the GeantGeoParams material if the geometry has been reloaded.

Return the optical ID corresponding to a geo ID.

The result may be a "null" ID if there's no associated optical physics.
