Fix scaling in LHCB_2010_S8758301. Speed up code.
Solve histogram scaling issues in finalize. Also speed up the code somehow by reducing PdgId to lifetime map size (only longest mother lifetime counts in prompt selection) and jumping over the pre-hadronization ancestors in the event tree scan. The attached file r3py83-c1M.zip contains the predictions from Pythia 8.303 out-of-box softQCD:all=on (1M) events. Please, let me know if you need further details.
