This project provides you with an opportunity to modify your work for
project 1 to raise your grade.  Your work on this project will be graded
on the same basis as project 1 (with one exception, below).  If the new
grade is higher than your original grade, your new grade will replace
the original grade.  If the new grade is not higher than your original
grade, your original grade stands as recorded.

If you decide not to turn in project 3, your grade for project 1 remains
unchanged.

Project 3

Start with the class diagram you created for project 2 and modify it to
improve the quality of your design.  [It's a good idea to take notes
about the changes you made as you do them.]

Once you are satisfied with your new design, modify the code that you
turned in for project 1 to match the new class diagram and then find
bugs that you introduced into the program as a result of your changes.

You will find that it is necessary to repeat all of the tests you used
for project 1 and, perhaps, add some new tests to cover cases that you
failed to test for in project 1.

Please turn in your revised program and your new class diagram via ftp
into your submission directory.
