	 Notes:
	
	 1. Use
	   ofile = outputFile(cmdline.outputfile, stream)
	
	 to skim events to output file in addition to writing out histograms.
	
	 2. Use
	   ofile.addEvent(event-weight)
	
	 to specify that the current event is to be added to the output file. If
	 omitted, the event-weight is taken to 1.
	
	 3. Use
	    ofile.count(cut-name, event-weight)
	
	 to keep track, in the count histogram, of the number of events passing
	 a given cut. If omitted, the event-weight is taken to be 1. If you want
	 the counts in the count histogram to appear in a given order, specify the
	 order, before entering the event loop, as in the example below
	 
	    ofile.count("NoCuts", 0)
		ofile.count("GoodEvent", 0)
		ofile.count("Vertex", 0)
		ofile.count("MET", 0)
