Added function to CommonCuts.py so we can do the matched mass-window cuts using index magic (can remove BDRSwin stuff from RunHTT and quickly test different mass windows now)
Removed BDRSwin/BDRSwin18 output from RunHTT.py
RunHTT.py: Added nsubitteness for CA fatjets. For the BDRS objects we can get it via matching to the CA jet
RunHTT.py: Renamed BDRS -> BDRS15
Added sorting according to lowest tau2/tau1 to MatchToGen.py
