REVISION HISTORY:
27/02/2014 : R. Bonventre - First version 22/02/2015 : R. Bonventre - Modified for RAT-PAC

VertexFile_Gen is used to take event vertices generated by RAT or any other program (for example GENIE atmospherics ) and simulate them in RAT. Unlike InRootProducer, which just runs RAT processors on fully simulated data, this generator lets you run Geant4 using just the MCParticle and MCParent information. To use this generator the command is /generator/add vertexfile filename[:POSITION][:TIME][:NEVENTS][:NOFFSET]

Where the file is any RAT root file that at least has MC particle information. If there is no POSITION or TIME or they are set to 'default' it will use the position / time given in the root file for that event. It will simulate NEVENTS of the events in the file, starting with event NOFFSET. If it runs out of events before you get through as many as specified with /rat/run/start, it will end the simulation after the completion of that event.
