1) Constant fraction discriminator added to the analysis of the
optical photon signal.
2) Bug fixes in the optical photon simulation.
3) A few other small improvements.
This is the first version of the muSR simulation code (musrSim)
based on the merged codes of Kamil Sedlak and Toni Shiroka.
It should be a running version of the simulation code, however
it has not been very well tested, therefore it will probably
need some further development.
