2017 incarnation of synchronisation
See here for instructions how to produce sync trees: https://twiki.cern.ch/twiki/bin/view/CMS/HiggsToTauTauWorking2017#Synchronisation
Please create a subfolder for a given analysis team, and add txt files (and sym links if you deem them useful) containing the latest sync files for a given channel and a short description (e.g. what's missing, what changed, etc)
