Detailed Description

Match reconstructed muons to HLT objects and plot efficiencies.

Note that this is not a true EDAnalyzer;

Documentation available on the CMS TWiki: https://twiki.cern.ch/twiki/bin/view/CMS/MuonHLTOfflinePerformance

Author

J. Slaunwhite, Jeff Klukas

Contanier class to handle vector of reconstructed muons matched to HLT objects used to plot efficiencies.

Note that this is not a true EDAnalyzer; rather, the intent is that one EDAnalyzer would call an instance of HLTMuonMatchAndPlotContainer
