   =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.
   
   =over 4
   
   =item show_previous_task_version()
   
   Displays a specified version of a student's Task, as the student sees it.
   
   Inputs: 2
           request - request object
           symb    - unique symb for current instance of resource
   
   Output: None.
   
   Side Effects: calls &show_problem() to print version of Task, with
                 version contained in form item: $env{'form.previousversion'}
   
   =item choose_task_version_form()
   
   Displays a web form used to select which version of a student's view of a
   Task should be displayed.  Either launches a pop-up window, or replaces
   content in existing pop-up, or replaces page in main window.
   
   Inputs: 4
           symb    - unique symb for current instance of resource
