Sessions and Results
Rename all model files containing capital letters
Added functionality to edit existing quizzes. The maximum number of answers is set to six.
This can easily be changed. I wasn't able to get the javascript for dynamic tabs so I just
added a new question tab at the start. Currently the delete function is not working. This
is due to the models not properly deleting. This can be fixed by updating the database or the models.
Also there is no validation of any kind I'm not sure what we might need to validate we can
talk at the meeting.
Added a done button. Added a way to edit quiz name. Added support for sessions. I wasn't able to
get any kind of "save all" working. When I put it all in one form it caused the loop to print all
the questions on one page. Also I added some basic checking tp make sure the user actually owns
the quiz before they can edit quizzes, delete questions or save quizzes.
