   (For this documentation 'scanline' refers to the full line of characters    For this documentation:
    from the file that we are parsing 'bubble line' refers to the data  
    representing the line of bubbles that are on the physical bubble sheet)  
   
 =over 4     'scanline' refers to the full line of characters
      from the file that we are parsing that represents one entire sheet
   
 =cut     '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.

   Prompts for a potentially multiline correction to the

   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 and matchresponse 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, forumalaresponse, and
                                     stringresponse 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.
