I changed and added a whole lot of stuff:
1.  I added code in the JavaMastersUI to change between questions.
2.  I added code to the QuestionNavigation that makes the buttons in the
Question list clickable.  When clicked they will change the page to that
problem.
3.  I modified my FillInTheBlank Class to accept more arguments in the
constructor.  And I cleaned it up a little.
4.  I created a MultpleAnswer problem type.
