Detailed Description

Create an ORANGE geometry model from an in-memory Geant4 model.

Return the new world volume and a mapping of Geant4 logical volumes to VecGeom-based volume IDs.

The default Geant4 "tolerance" (often used as surface "thickness") is 1e-9 mm, and the relative tolerance when specifying a length scale is 1e-11 (so the default macro length scale is expected to be 100 mm = 10 cm). That relative tolerance is much too small for any quadric operations or angular rotations to be differentiated, so for now we'll stick with the ORANGE default tolerance of 1e-8 relative, and we assume a 1mm length scale.
