public class HistoMatcher
extends java.lang.Object

Use this class to rescale a set of byte arrays to have the the same values at two points in the histogram of values. Generate the HistMatcher with the values (0-1) at which you want the histograms to mach. Add in the arrays with calls to addList. Call calc to generate the average values. call rescale(n) to get a rescaled array.
