Detailed Description

Unique placement/replica of a Geant4 physical volume.

This should correspond to a VolumeInstanceId and be a unique instantiation of a Geant4 physical volume (PV). Some Geant4 PVs are "parameterised" or "replica" types, which allows a single instance to be mutated at runtime to form a sort of array. If the pointed-to physical volume is not a replica/parameterised volume, replica is false. Otherwise, it corresponds to the PV's copy number, which can be used to reconstruct the placed volume instance.

Todo:

This will be replaced by a VolumeInstanceId when GeantGeoParams stores a mapping between the canonical geometry definition and its internal parametrised representation.
