 Description: Muon Isolation DQM class

 Implementation: This code will accept a data set and generate plots of
    various quantities relevent to the Muon Isolation module. We will 
    be using the IsoDeposit class, *not* the MuonIsolation struct.
     
    The sequence of events is... 
        * initalize statics (which variables to plot, axis limtis, etc.)
        * run over events
            * for each event, run over the muons in that event
                *record IsoDeposit data
        * transfer data to histograms, profile plots
        * save histograms to a root file
