   Retreives the current submitted response, helps out in the case of
   scantron mode.
   
   Returns either the exact text of the submission, or a bubbled response
   converted to something usable.
   
   Optional Arguments:
     $offset - (defaults to 1) if a problem has more than one bubble
               response, pass in the number of the bubble wanted, (the
               first bubble associated with a problem has an offset of 1,
               the second bubble is 2
   
     $resulttype - undef    -> a number between 0 and 25
                   'A is 1' -> a number between 1 and 26
                   'letter' -> a letter between 'A' and 'Z'
     $lines  - undef problem only needs a single line of bubbles.
               nonzero  Problem wants the first nonempty response in 
                         $lines lines of bubbles.
     $bubbles_per_line - Must be provided if lines is defined.. number of
                         bubbles on a line.
