+=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
