	scan_data - Hash of extra information about the scanline
	(see scantron_getfile for more information)
	just_header - True if should not process question answers but only

	forced by the operator
	ID - student ID
	PaperID - if used, the ID number printed on the sheet when the
	paper was scanned
	FirstName - first name from the sheet
	LastName - last name from the sheet

	if just_header was not true these key may also exist

	missingerror - a list of bubbled line numbers that had a blank bubble
	that is considered an error (if the operator had already
	okayed a blank bubble line as really being blank then
	that bubble line number won't appear here.
	doubleerror - a list of bubbled line numbers that had more than one
	bubble filled in and has not been corrected by the
	operator
	maxquest - the number of the last bubble line that was parsed

	(<number> starts at 1)
	<number>.answer - zero or more letters representing the selected
	letters from the scanline for the bubble line
	<number>.
	if blank there was either no bubble or there where
	multiple bubbles, (consult the keys missingerror and
	doubleerror if this is an error condition)

	=item scantron_process_students

	Routine that does the actual grading of the bubble sheet information.

	The parsed scanline hash is added to %env

	Then foreach unskipped scanline it does an &Apache::lonnet::ssi()
	foreach resource , with the form data of

	'submitted' =>'scantron'
	'grade_target' =>'grade',
	'grade_username'=> username of student
	'grade_domain' => domain of student
	'grade_courseid'=> of course
	'grade_symb' => symb of resource to grade

	This triggers a grading pass. The problem grading code takes care
	of converting the bubbled letter information (now in %env) into a
	valid submission.
