[G14_run] 4vecs for testing

[Haiyun Lu]

As discussed, I attached a 100-event text file. Each event has three 
particles: photon beam, scattered proton and scattered pi- in order. 
Each particle occupies one line with energy, momentum in x direction, 
momentum in y, and momentum in z. All these variables are in Lab frame. 
There are totally 300 lines.
