few more histos...
added findZ flag (and not used)
added findZ ...
Problem solved!
here is why it crushed. in the VecBosRootFile class (called by VecBosAsymRootFile) it is now declared the flag isZ which is passed from vbana.cc

when you run vbana.cc now set this flag TRUE if you want to run over Zs. You also have to change WBosEvent() to ZBosEvent()

for this look at the new version of vbana.cc
