<CODE>ProgramDiffTest</CODE> tests the <CODE>ProgramDiff</CODE> class
to verify it correctly determines various types of program differences.
The setup for this test class loads two programs that were saved to the
testdata directory as XML. The tests will determine the differences between
these two programs.
