// Class G4GeometryCellStep
//
// Class description:
//
// This class serves to address the "cell" a track previously 
// touched and a "cell" a track is currently in. It is used 
// for scoring and importance sampling in the "mass" geometry as well 
// as in a "parallel" geometry. 
// The "cell" information is available with the GetPreGeometryCell and 
// the GetPostGeometryCell functions.
// The GetCrossBoundary finction returns true in case the step
// crosses a boundary in the geometry this G4GeometryCellStep 
// refers to.
