4 // MuonTools
5 //
6 // This class allows you to classify a given muon according to defined criteria. For this purpose
7 // is loads histograms from two ROOT files, specified in the constructor. The main function then
8 // is "IsGood(*muon, selection)" which returns true if the given muon fulfills the selection
9 // criteria.
10 //
11 // Logically, the code has been put together by Phil who took most of the ideas from
12 // http://cmslxr.fnal.gov/lxr/source/RecoMuon/MuonIdentification/
