Status of cosmics simulation for ID barrel

• Current samples can be found on lxplus203/tmp/chriss/else/dig_*.root 50 samples of 50k generated events each were submitted, yielding a average of ~60 events passing the simulation and digitization. 4 samples had problems and are not available. .
  
• Procedure use is described here with a few exceptions:

in jobOptions.G4Cosmic_WriteTTR_custom.py instead of just

 include("G4CosmicFilter/G4CosmicFilter.py") 

a new filter volume was defined as

MenuRecordEnvelopes=AtlasG4Eng.G4Eng.menu_RecordEnvelope()
recenv=PyG4Atlas.RecEnvelope('TRTBarrelEntryLayer','TRT::BarrelOuterSupport',6)
MenuRecordEnvelopes.add_RecEnvelope(recenv)
include("G4CosmicFilter/G4CosmicFilter.py")

This recording volume was then also specified in G4CosmicFilter/G4CosmicFilter.py
In addition, the default parameters in myConfig.py were:

CosmicGenerator.xvert_low =   -200000.
CosmicGenerator.xvert_hig =    200000.
CosmicGenerator.zvert_low =    -200000.
CosmicGenerator.zvert_hig =    200000.
CosmicGenerator.Radius=10000. #barrel lenght ~22m
