Checks classlist for section number, id & fullname. If not present, will
rewrite the classlist.
Remove a few buttons for keywords highlight etc.
Receipt button works - also provides a link to view the student's page if
verified.
On the whole, pretty much complete for grading by class, or individually.
csv needs to be checked.
