v 1.4 with better pregenerated file managament

v1.4 many small bug fixes/changes as well as:

--fixed a bug which broke random trigger merging for c shell users

--incorporated David L's suggestion; now if you have a pre-generated file of events (say 1M events) each of the 100 default sub-job will run over a different chunk of the data.

--fixed an issue in which files already present at run time would be treated as job output and be moved. Now, any files that exist at the start of the run should not be picked up and moved

--more targeted moving/cleaning of files generated by the wrapper

--new output directory structure. Now, the configurations folder contains two sub-folders: "generation" which will contain each subjob's configuration file used in the generation step and "geant" which contains each sub-job's control.in file.

--inclusion of gen_omega_3pi generator. See the Generator/.../examples/ folder for example configuration files
