/**
 * A class to compare vectors of objects.  The result of comparison
 * is a list of <code>change</code> objects which form an
 * edit script.  The objects compared are traditionally lines
 * of text from two files.  Comparison options such as "ignore
 * whitespace" are implemented by modifying the <code>equals</code>
 * and <code>hashcode</code> methods for the objects compared.
 * <p/>
 * The basic algorithm is described in: </br>
 * "An O(ND) Difference Algorithm and its Variations", Eugene Myers,
 * Algorithmica Vol. 1 No. 2, 1986, p 251.
 * <p/>
 * This class outputs different results from GNU diff 1.15 on some
 * inputs.  Our results are actually better (smaller change list, smaller
 * total size of changes), but it would be nice to know why.  Perhaps
 * there is a memory overwrite bug in GNU diff 1.15.
