Detailed Description

A lighter VecGeom navigator for Geant4, selected with G4.vecgeomNavigator=kPropagated. ComputeStep uses VecGeom's combined step-and-relocate, and a boundary locate adopts the state that step propagated instead of locating again. Safety is zero for the whole step after a crossing, a stuck step is nudged forward, and the exit normal follows the direction of motion. It does less work per step and per crossing than VecGeomG4Navigator.
