   For bubble grading mode and exam bubble printing mode, the tracking of
   the current 'bubble line number' is stored in the %env element
   'form.counter', and is modifed and handled by the following routines.
   
   The value of it is stored in $Apache:lonxml::counter when live and
   stored back to env after done.
