This package implements the particle ID that Tricia and I have done "by
hand" in a form that anyone should be able to use.  Without knowing time
of flight, cerenkov, beam momentum, etc you will be able to use a macro to
ask for a stream of electrons, pions||muons or protons.  This is all very 
nice but:

THIS PACKAGE IS NOT VETTED. I WILL NOT STAND BY THE RESULTS YET!

It should compile and run however. If you want to say, look at some caldet 
events in a display, then by all means try it out.  You might even help 
the author find a bug.  If you want to use it to study pi zero production 
for your slick talk at the next collaboration meeting, I DON'T RECOMMEND 
IT!
