Huge update.  Navigation works.  The display works.  Saving data into an XML file works (loading from one does not work yet).  Moved the temporary testing data into a new class.  Working currently on the XML file.  I can make it, but I think when I save it just adds another <root> tag after the end of the first <root> </root> tag.  So I have to make sure that it is being oversaved correctly.  I also have to be able to load data correctly. I am working on that.
