Features 1 to 4 are done.
To implement assign quiz, we should do the following:

1. In see_quiz, add a button for "assign quiz"
2. On clicking assign quiz, a list of users should how up with a check mark against each user name.
3. A button "Save" shoudl appear at the bottom. On hitting this button, an entry is made in the quiz object with the name "assignedToUserID" that has a list of userIDs to whom the quiz is allotted.
4. When the see_quiz screen is displayed again, the quiz that has been assigned to a user will appear first.
5. When a user finishes a quiz, the user name is removed from the assignedToUserID entry.
