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. |
