Make this thing work on JETM2
Some people in the jet group might be interested in using this thing for things. In particular @mleblanc put a JETM2
file here:
/afs/cern.ch/work/m/mleblanc/public/JETM2_Test/DAOD_JETM2.31343438._000001.pool.root.1
My understanding is that we're mostly interested in dumping the jet constituents: probably just 4 momenta.
