public class Difference
extends java.lang.Object

This class is modified from Difference.java from incava.org. It represents a difference, as used in Diff.java. A difference consists of two pairs of starting and ending points, each pair representing either the "from" or the "to" collection passed to Diff class. If an ending point is -1, then the difference was either a deletion or an addition. For example, if GetDeletedEnd() returns -1, then the difference represents an addition; if GetAddEnd() returns -1, then the difference represents an deletion.
