+// Class G4PStep
+//
+// 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 fPreTouchableKey and the 
+// fPostTouchableKey.
+// The fCrossBoundary member is set true in case the step
+// crosses a boundary in the geometry it this G4PStep 
+// refers to.
