Detailed Description

Update a nav history to match the given volume instance stack.

This requires metadata from celeritas::global_geant_geo .

The constructed nav history always has at least one level (i.e. GetDepth is zero). An empty input stack, corresponding to "outside" the world, results in a nav history with one level but a nullptr physical volume as the top.

Note

The stack should have the same semantics as VolumeLevelId, i.e. the initial entry is the "most global" level.
