Added Mockito to the path and lib folder for unit testing fun.
Added com.socialsoftsys.bureaucrat.model.ModuleObjectTest, although the functionality of the class it tests is small enough to not really need mocking, as it runs with an interface I figured why not use it demonstrate mocking. Next commit should be tests for at least a few others in the same package.
EnumUtilTest, showcasing how mocks can be used efficiently to verify somewhat complex behavior. Additionally, Mock tests of ModuleObject and ModelObject show how esoteric they are, with very ltitle purpose (at least, as of now). Awaiting explanations as to their purposes / may be refactored.
