Builds the interface screen to interact with the operator to fix a
specific error condition in a specific scanline

Arguments:
$r - Apache request object
$i - number of the current scanline
$scan_record - hash ref as returned from &scantron_parse_scanline()
$scan_config - hash ref as returned from &get_scantron_config()
$line - full contents of the current scanline
$error - error condition, valid values are
'incorrectCODE', 'duplicateCODE',
'doublebubble', 'missingbubble',
'duplicateID', 'incorrectID'
$arg - extra information needed
For errors:
- duplicateID - paper number that this studentID was seen before on
- duplicateCODE - array ref of the paper numbers this CODE was
seen on before
- incorrectCODE - current incorrect CODE
- doublebubble - array ref of the bubble lines that have double
bubble errors
- missingbubble - array ref of the bubble lines that have missing
bubble errors

	=item prompt_for_corrections

	Prompts for a potentially multiline correction to the
	user's bubbling (factors out common code from scantron_get_correction
	for multi and missing bubble cases).

	Arguments:
	$r - Apache request object.
	$question - The question number to prompt for.
	$scan_config - The scantron file configuration hash.
	$scan_record - Reference to the hash that has the the parsed scanlines.
	$error - Type of error

	Implicit inputs:
	%bubble_lines_per_response - Starting line numbers for each question.
	Numbered from 0 (but question numbers are from
	1.
	%first_bubble_line - Starting bubble line for each question.
	%subdivided_bubble_lines - optionresponse, matchresponse and rankresponse
	type problems render as separate sub-questions,
	in exam mode. This hash contains a
	comma-separated list of the lines per
	sub-question.
	%responsetype_per_response - essayresponse, formularesponse,
	stringresponse, imageresponse, reactionresponse,
	and organicresponse type problem parts can have
	multiple lines per response if the weight
	assigned exceeds 10. In this case, only
	one bubble per line is permitted, but more
	than one line might contain bubbles, e.g.
	bubbling of: line 1 - J, line 2 - J,
	line 3 - B would assign 22 points.

=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.

	=head1 NAME

	Apache::grades

	=head1 SYNOPSIS

	Handles the viewing of grades.

	This is part of the LearningOnline Network with CAPA project
	described at http://www.lon-capa.org.

	=head1 OVERVIEW

	Do an ssi with retries:
	While I'd love to factor out this with the vesrion in lonprintout,
	that would either require a data coupling between modules, which I refuse to perpetuate (there's quite enough of that already), or would require the invention of another infrastructure
	I'm not quite ready to invent (e.g. an ssi_with_retry object).

	At least the logic that drives this has been pulled out into loncommon.



	ssi_with_retries - Does the server side include of a resource.
	if the ssi call returns an error we'll retry it up to
	the number of times requested by the caller.
	If we still have a proble, no text is appended to the
	output and we set some global variables.
	to indicate to the caller an SSI error occurred.
	All of this is supposed to deal with the issues described
	in LonCAPA BZ 5631 see:
	http://bugs.lon-capa.org/show_bug.cgi?id=5631
	by informing the user that this happened.

	Parameters:
	resource - The resource to include. This is passed directly, without
	interpretation to lonnet::ssi.
	form - The form hash parameters that guide the interpretation of the resource

	retries - Number of retries allowed before giving up completely.
	Returns:
	On success, returns the rendered resource identified by the resource parameter.
	Side Effects:
	The following global variables can be set:
	ssi_error - If an unrecoverable error occurred this becomes true.
	It is up to the caller to initialize this to false
	if desired.
	ssi_error_resource - If an unrecoverable error occurred, this is the value
	of the resource that could not be rendered by the ssi
	call.
	ssi_error_message - The error string fetched from the ssi response
	in the event of an error.


	=head1 HANDLER SUBROUTINE

	ssi_with_retries()

	=head1 SUBROUTINES

	=over

	=item scantron_get_correction() :

	Builds the interface screen to interact with the operator to fix a
	specific error condition in a specific scanline

	Arguments:
	$r - Apache request object
	$i - number of the current scanline
	$scan_record - hash ref as returned from &scantron_parse_scanline()
	$scan_config - hash ref as returned from &get_scantron_config()
	$line - full contents of the current scanline
	$error - error condition, valid values are
	'incorrectCODE', 'duplicateCODE',
	'doublebubble', 'missingbubble',
	'duplicateID', 'incorrectID'
	$arg - extra information needed
	For errors:
	- duplicateID - paper number that this studentID was seen before on
	- duplicateCODE - array ref of the paper numbers this CODE was
	seen on before
	- incorrectCODE - current incorrect CODE
	- doublebubble - array ref of the bubble lines that have double
	bubble errors
	- missingbubble - array ref of the bubble lines that have missing
	bubble errors

	=item scantron_get_maxbubble() :

	Returns the maximum number of bubble lines that are expected to
	occur. Does this by walking the selected sequence rendering the
	resource and then checking &Apache::lonxml::get_problem_counter()
	for what the current value of the problem counter is.

	Caches the results to $env{'form.scantron_maxbubble'},
	$env{'form.scantron.bubble_lines.n'},
	$env{'form.scantron.first_bubble_line.n'} and
	$env{"form.scantron.sub_bubblelines.n"}
	which are the total number of bubble, lines, the number of bubble
	lines for response n and number of the first bubble line for response n,
	and a comma separated list of numbers of bubble lines for sub-questions
	(for optionresponse, matchresponse, and rankresponse items), for response n.


	=item scantron_validate_missingbubbles() :

	Validates all scanlines in the selected file to not have any
	answers that don't have bubbles that have not been verified
	to be bubble free.

	=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.

	=item scantron_upload_scantron_data() :

	Creates the screen for adding a new bubble sheet data file to a course.

	=item scantron_upload_scantron_data_save() :

	Adds a provided bubble information data file to the course if user
	has the correct privileges to do so.

	=item valid_file() :

	Validates that the requested bubble data file exists in the course.

	=item scantron_download_scantron_data() :

	Shows a list of the three internal files (original, corrected,
	skipped) for a specific bubble sheet data file that exists in the
	course.

	=item scantron_validate_ID() :

	Validates all scanlines in the selected file to not have any
	invalid or underspecified student IDs
