QuizKeeper plugin

It is primarily for teachers to use. I needed a plugin that will allow teachers to create quizzes and manage grades that students have taken. I couldn’t find a quiz plugin out there that could do this so I made one.

I developed this plugin over the course of a few months for a client and it is my first plugin. I am uploading it here for developer use and it comes as-is. I am looking for input more than anything. I have spent more time changing code the last few weeks and I have come to the conclusion that it is due to my lack of experience in actual OOP. So if you are a developer and you want something to do, check it out!

It is a functional plugin and works fine so if you are a teacher and you would like to try it out, feel free. Like I said, it is as-is, and I am really just looking for developer input as to what I should fix or change. (Security issues, readability, organization, etc.)

Please please please make sure you back up your database and installation before installing this plugin. If you look at the install file you will notice that I create 5 tables (qk_answers, qk_questions, qk_quizzes, qk_logs, and qk_grades). I add 2 options to the wp_options table (qk_final_screen and qk_version). These are the only database alterations and I did it this way to keep it away from the wordpress install as much as possible. Too often do plugins break an installation.

If I am breaking any rules on linking stuff or something just remove the post. Thanks community!

edit: I am posting this here for 2 reasons:
1. QuizKeeper on GitHub
2. It is way to beta to be worth uploading to the actual public.
