   Retreives the current submitted response, helps out in the case of

   Returns either the exact text of the submission, or a bubbled response
   converted to something usable.
   
   Optional Arguments:

               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'
