   =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 bubble sheet
   
   
   The overall process is that a scanned in bubble sheet data is uploaded
   into a course. When a user wants to grade, they select a
   sequence/folder of resources, a file of bubble sheet 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 ID
   
   If the CODE option is used that determines the randomization of the
   homework problems, either way the student 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 bubble sheet 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 bubble sheet
   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.

   =item scantron_parse_scanline
   
     Decodes a scanline from the selected scantron file
   
    Arguments:
       line             - The text of the scantron file line to process
       whichline        - Line number
       scantron_config  - Hash describing the format of the scantron lines.
       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
                          the stuff to the left of the answers.
    Returns:
      Hash containing the result of parsing the scanline
   
      Keys are all proceeded by the string 'scantron.'
   
          CODE    - the CODE in use for this scanline
          useCODE - 1 if the CODE is invalid but it usage has been forced
                    by the operator
          CODE_ignore_dup - 1 if the CODE is a duplicated use when unique
                               CODEs were selected, but the usage has been
                               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 bubble ranges that are considered to be answers
                         to a single question that don't have any bubbles filled in.
                         Of the form questionnumber:firstbubblenumber:count.
          doubleerror  - a list of bubble ranges that are considered to be answers
                         to a single question that have more than one bubble filled in.
                         Of the form questionnumber::firstbubblenumber:count
      
                   In the above, count is the number of bubble responses in the
                   input line needed to represent the possible answers to the question.
                   e.g. a radioresponse with 15 choices in an answer sheet with 10 choices
                   per line would have count = 2.
   
          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)

      $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

   =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() : 
   
      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
