- introduced modifications done by Pavel Bakule at ISIS:
       a)  the time when the initial muon is generated can be
           set according to a gaussian or flat distribution.
           (all muons were generated at time 0 before this change).
       b)  a new volume "cylpart" has been added.
   The code can be compiled, but no tests of the newly implemented
   features have been done.  In future, the information about the
   time of the muon generation should be added to the root output
   tree.
