 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.
