1) correction of GNUmakefile - by mistake a musrSimTest was set there
   instead of musrSim
2) replacing odet_timeE variable by odet_timeMean
3) replacing one obsolete method from stepping action
   (Geant 4.9.4 was complaining) by a proper method
4) update of the first part of the documentation
5) implementing a possibility to write out output Root data
   into a different directory
6) perhaps some other minor changes
