   Prompts for a potentially multiline correction to the

    Arguments:
      $r           - Apache request object.

      $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.

                                     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,

   =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.

   =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().
   
      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/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.
