Validation for NEUT pion production: just takes output MC ROOT file and plots various distributions.
Takes input events, classifies them according to signal definitions, and gets various kinematic distributions of interest.
Supports CC0pi, CC1pi0, CC1pi+ signal definitions.
Very hacked for now: most executables to very similar things. getKin and getKin_nuc do the kinematics for a nuclear target and a nucleon target. Should really move to a class system later.
For similar stuff (but much more extensive) see NUISANCE.
