Detailed Description

Map a string or Geant4 volume pointer to a volume ID.

This std::visit -compatible class will convert input types to a canonical volume ID depending on what metadata (constructed Geant4 geometry, volume parameters) are available. A "null" ID can be returned (and warning/error message emitted) if the mapping fails.

This helper class should only have temporary scope.
