Added new subdirectory (analysis package) "musrSimAna". This is
a general analysis program that allows one to plot histograms
out of the simulated trees. The detector setup of the veto and
coincidence relations with the positron/muon counters is defined
in *.v1190 files. Also the histograms that should be plotted/saved
are defined in this file.
Thus (at least in principle) the user does not need to write
an analysis program dedicated for his/her instrument. One just
needs to modify the *.v1190 file. The "musrSimAna" is still
in the development phase, no documentation is available at this
stage.
