-- Updated model to allow for simpler submission of multiple answers edited marking class to accomodate, this will need a change in the add question UI.
-- This means the constructore of MCQuestion and FITBQuestion have been extended to accomodate such changes.
-- Updated Take test ui, root class is "PaperView" at the moment, I suggest that when this is encorporated into UI it can be changed to a more suitable name.
-- Currently PaperView and SectionView have buttons that are declared locally and update the frame locally. If you can do this in the controller that'd be nice.
