Setup g2p environment

This is the wiki guide to setup geant4 environment on ifarm, also you can use it on your level 1/level 2 64bit computer if you have already mounted the g2p work disk on it. For bash shell, you need to build the environment by yourself, the software can be found in /w/halla-1/g2p/software.

1.Setup root. You can simply type the command of:

 source /w/halla-1/g2p/software/setupg2penv.csh
