// pseudo code for how to use this in analysis:
//
// std::vector<genTop> tops;  
// std::vector<Jet> tagged_jets; 
// double weight = 1;
//
// for(const auto & jet: tagged_jets){ 
//   ToptaggingSFs::eCategory cat = getTopTaggingMatch(tops, jet);
//   weight *= ToptaggingSFs::readScaleFactor(ToptaggingSFs::PUPPI_wp2_btag, true, 2016, cat, jet.pt(), ToptaggingSFs::nominal);
// }
//
// now multiply this weight with all other reco event weights
