Muon tests failing on Linux with Geant4 10.1 and 10.2

[Jochem Snuverink]

The muon tests muon_e- and muon_e+ are segfaulting on Linux with Geant4 10.1 and 10.2 (on mac and 10.0 they run). See, e.g. http://abp-cdash.web.cern.ch/abp-cdash/index.php?project=BDSIM&date=2016-04-15 The physics list is:

physicsList="em em_extra hadronic_elastic QGSP_BERT muon";

and the stacktrace:

definitely happens with physics list "muon". Improved traceback on 10.2.0

This happens for the process G4Cerenkov. Not all relevant particles were defined in ConstructParticle(). These are added now.

I have the feeling that MuonPhysics needs to be reviewed at some point.

[Jochem Snuverink]

fix issue #130: construct relevant particles

The previous commit was not working, possibly I had fooled myself by adding the optical process which also fixed the tests. Two other commits were needed f815254 and 12af12b. The former for an uninitialised value on hadronic_elastic and the latter to switch on Scintillation for muons when Cerenkov is on.

[Jochem Snuverink]

still failing on Geant4 10.1

[Jochem Snuverink]

fixed by commit 1623aa4 : switching on Cerenkov radiation and scintillation also for elec/positrons when on for muons; prevents the crash in 10.1
