Switching to eclipseLink, added interfaces for the persistables, most
likely not needed, but I am following a pattern I use elsewhere, so why
not just put them in.  Next step would be to finish the interfaces with
the method stubs needed, and then work on the service classes and
EntityFactory.  After that, I really want to get started on a GUI
design.  I am going to be copying my language configuration classes from
BudgIt V2.
