	=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
	uname - username of student
	udom - domain of student
	nomenu - 1 if display is in a pop-up window, and hence no menu
	breadcrumbs etc., are displayed

	Output: 4
	current - student's current version
	displayed - student's version being displayed
	result - scalar containing HTML for web form used to switch to
	a different version (or a link to close window, if pop-up).
	js - javascript for processing selection in versions web form

	Side Effects: None.

	=item previous_display_javascript()

	Inputs: 2
	nomenu - 1 if display is in a pop-up window, and hence no menu
	breadcrumbs etc., are displayed.
	current - student's current version number.

	Output: 1
	js - javascript for processing selection in versions web form.
