The correction for SF events with two nucleons in the final state. Some cleanup in cascade. New classes in ganalysis files.
IFIC MEC model has now separate tables for Calcium40. Targets with >15 protons are assumed
to have cross section/nucleon from Calcium table in IFIC model.
Calculation of local Fermi momentum corrected.
Fixed bug for antineutrino Valencia MEC nucleon isospin content
Minor isospin content bug fix
