| In this section we add examine input/output features for our histograms. 
              We want to add to the histogram classes the ability to save histograms 
              to disk files and then to read back the data from these files and 
              rebuild the histograms. We show a couple of different ways to do 
              this. We also look at using stream filtering as a way to modify 
              data, such as calibrating raw data, as it is read into a histogram.. 
              Histogram Input/Output - use writing 
                and reading histograms as an example of basic I/O techniques Histogram I/O - uses getter 
                methods to obtain the data for saving the histogram and setter 
                methods to create new histogram with values retrieved from the 
                data files. 
                
              Hist I/O with Objects - use serialization 
                to send and receive objects. 
                
              Histogram Stream - send a stream 
                of data to a histogram. That is, the histogram becomes the destination 
                for the stream. 
                
              Histogram Filtering - filter 
                a stream of data going to a histogram destination.
