Detailed Description

Classify and filter events according to Higgs boson decays

   Reads:
     event.genHiggsBosons

   Creates in the event:
     event.genHiggsDecayMode =   0  for non-Higgs or multi-higgs
                             15  for H -> tau tau
                             23  for H -> Z Z
                             24  for H -> W W
                             xx  for H -> xx yy zzz 
   If filterHiggsDecays is set to a list of Higgs decay modes,
   it will filter events that have those decay modes.
   e.g. [0, 15, 23, 24] will keep data, non-Higgs MC and Higgs decays to (tau, Z, W) 
   but will drop Higgs decays to other particles (e.g. bb).
