   B<Simple Status>
   
   Convenience method B<simpleStatus> provides a "simple status" for the resource.
   "Simple status" corresponds to "which icon is shown on the
   Navmaps". There are six "simple" statuses:
   
   =over 4
   
   =item * B<CLOSED>: The problem is currently closed. (No icon shown.)
   
   =item * B<OPEN>: The problem is open and unattempted.
   
   =item * B<CORRECT>: The problem is correct for any reason.
   
   =item * B<INCORRECT>: The problem is incorrect and can still be
   completed successfully.
   
   =item * B<ATTEMPTED>: The problem has been attempted, but the student
   does not know if they are correct. (The ellipsis icon.)
   
   =item * B<ERROR>: There is an error retrieving information about this
   problem.
