//      Seperation into DriftCellBack and DriftCellFront for testing purpose.
//
//      Revision 1.3  2006/01/02 13:24:22  grimm
//      Commenting the originVertexPosition cut (z> 635*cm). Now I'm allowing to record all charged hits of the drift cell regardless of the vertex origin.
//      (With the target cut I got ~20k drift cell hits out of 300k primary events. The wire planes without origin cut get a hit quote of 30%)
//
//      Revision 1.2  2005/12/27 19:19:16  grimm
//      - Redesign of Doxygen header containing CVS info like revision and date
//      - Added CVS revision log at the end of file
