added copies of a few histograms that I like to have at born level, not passing trough the /utils
update and fix the branches also for the sf2 git branch.
I now use a sample Wp file for the Pt correction. This is in the dir:
/star/institutions/bnl_me/fazio/vbana_out/ptcorr_samples

this not to interfere when I run vbana over W+->ev MC trees
remove no longer used branches
