Create public and private wiki feature with form

John -

Here is the 'user creates a wiki' feature, which I have tested manually. It does correctly flag the wiki as private when the box is checked by the user. Also, I did confirm that a user can only see their own wikis once created. Note I have not done the collaborations part yet.

This includes the work we did on the call today as well as some form prettying.

Thanks,
Michelle
