+=head1 Bubble sheet grading routines
+
+  For this documentation:
+
+   'scanline' refers to the full line of characters
+   from the file that we are parsing that represents one entire sheet
+
+   'bubble line' refers to the data
+   representing the line of bubbles that are on the physical bubblesheet
+
+
+The overall process is that a scanned in bubblesheet data is uploaded
+into a course. When a user wants to grade, they select a
+sequence/folder of resources, a file of bubblesheet info, and pick
+one of the predefined configurations for what each scanline looks
+like.
+
+Next each scanline is checked for any errors of either 'missing
+bubbles' (it's an error because it may have been mis-scanned
+because too light bubbling), 'double bubble' (each bubble line should
+have no more that one letter picked), invalid or duplicated CODE,
+invalid student/employee ID
+
+If the CODE option is used that determines the randomization of the
+homework problems, either way the student/employee ID is looked up into a
+username:domain.
+
+During the validation phase the instructor can choose to skip scanlines. 
+
+After the validation phase, there are now 3 bubblesheet files
+
+  scantron_original_filename (unmodified original file)
+  scantron_corrected_filename (file where the corrected information has replaced the original information)
+  scantron_skipped_filename (contains the exact text of scanlines that where skipped)
+
+Also there is a separate hash nohist_scantrondata that contains extra
+correction information that isn't representable in the bubblesheet
+file (see &scantron_getfile() for more information)
+
+After all scanlines are either valid, marked as valid or skipped, then
+foreach line foreach problem in the picked sequence, an ssi request is
+made that simulates a user submitting their selected letter(s) against
+the homework problem.

+=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 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() : 
+
+   Arguments:
+       $nav_error  - Reference to scalar which is a flag to indicate a
+                      failure to retrieve a navmap object.
+       if $nav_error is set to 1 by scantron_get_maxbubble(), the 
+       calling routine should trap the error condition and display the warning
+       found in &navmap_errormsg().
+
+       $scantron_config - Reference to bubblesheet format configuration hash.
+
+   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 bubblesheet 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 bubblesheet 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 bubblesheet 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/employee IDs
+
+=item navmap_errormsg() :
+
+   Returns HTML mark-up inside a <div></div> with a link to re-initialize the course.
+   Should be called whenever the request to instantiate a navmap object fails.
