   =head1 Routines to display previous version of a Task for a specific student
   
   Tasks are graded pass/fail. Students who have yet to pass a particular Task
   can receive another opportunity. Access to tasks is slot-based. If a slot
   requires a proctor to check-in the student, a new version of the Task will
   be created when the student is checked in to the new opportunity.
   
   If a particular student has tried two or more versions of a particular task,
   the submission screen provides a user with vgr privileges (e.g., a Course
   Coordinator) the ability to display a previous version worked on by the
   student.  By default, the current version is displayed. If a previous version
   has been selected for display, submission data are only shown that pertain
   to that particular version, and the interface to submit grades is not shown.
