First draft done

Today at work I wrote the last of six test suites for the assignment students will work on over the course of the fall semester. Despite checking the simplest behavior, it was one of the more complicated test suites because the logic implemented by students in its segment gets refactored/rearranged later, so the tests need to be able to find and invoke the student code appropriately. Tomorrow I plan to heavily comment the starter code and put together enough instructions for other course staff to start testing it.
