   =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.

       $key        - shorthand of the key to edit (actual key is
                     scantronfilename_key).
       $data        - New value of the hash entry.

   =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)
