// 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() function returns true in case the step
// crosses a boundary in the geometry this G4GeometryCellStep 
// refers to.
