 Description: Muon Isolation Validation 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
                
        Easy-peasy.
