6 loizides 1.4 // 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/
