Cookie Work

 I think I got all the cookie references, there are still chocolate chips all over the floor.  Also, I tried to style my code like the code already present.

1. Added cookie code.  Seems like it shouldn't be this simple, but it worked in the tests I did.

2. Changed group strings to an associative array as I think it greatly improves readability.

3. Added a groups data file using json file type.  I've been using it a lot for my project but it would be easy to change to a different format if you prefer.  I prefer to separate things like this from my code, again for the sake of readability.

4. Fixed a couple spelling mistakes I saw.
