Add functor for NeutralE19
Add a NEUTRALE19
functor to NeutralLike.h
to access the ratio of the seed cell to the 9 cells in the 3x3 cluster.
Functor added to TestFunctors.cpp
as well.
Needed to improve the selection in the pi0 monitoring.
FYI @dzhang @yagao this can be useful in your Moore scripts for the pi0 calibration FYI @tnanut @mramospe @poluekt @mvesteri
