Analysis production for b2stautau with MuE end-state (Run 2 data)

Analysis production for b -> s tau tau, with one tau decaying to an electron (and neutrinos) and one tau decaying to a muon (and neutrinos). The s-quark is contained in a dihadron system; either KK (Bs -> KKtautau) or Kpi (B0 -> Kpitautau). These are contained in different branches. Further branches are also present for decays with reverse PID requirements, same-sign leptons and same-sign hadrons. This production runs over 2016, 2017 and 2018.
