// Modified: 31.05.2006 by O. Kortner: major redesign:
//                                     driftvelocity implemented,
//                                     resolution has been removed,
//                                     set-method have been removed
//           04.06.2006 by O. Kortner: bug in constructor fixed,
//                                     doxygen entry updated.
