I talked to Alex about this, and we shouldn't need the UI package if we are not testing the GUI (which we aren't with our Arquillian tests). 
But apprently we have a `WordStatistics` class that gets used in the UI but gets produced in the server. I initially created the UI package to place anything that we only want used from the UI (that is xhtml or Action classes), and this class seems to violate that proposition. We need to consider moving this class to a different package.
