remove fast objects
add __str__ to reco::GenParticle and remove legacy GenParticle/GenLepton
fix typo in autovars showing up when isMC = False
Add default configs and option to store individual bits for trigger studies
reusing Particle.__str__ seem not to work. better would be to have a free function baseP4Printing to be shared for different cases
Merge pull request #11 from arizzi/heppy_7_2_2_patch2

Thanks!
