Clean up jsons -- ana_all.json is now for LS with L1_QuadJetC40 and HLT_QuadJet50_v* unmasked and unprescaled and corresponds to 17.65/fb with current pixelLumiCalc.
setup_endpath: fix case where weight_src is empty.
Hardcode to L1_QuadJetC40 and HLT_QuadJet50_v{1,2,3,5}; add require_muon option and corresponding plots; genjets; sumht; only run on the 17.65/fb.
