 //        This class sits between instances of DictionaryBasedBreakIterator

 //        and the dictionary data itself,  which is of type BreakDictionary.

 //        It provides reference counting, allowing multiple copies of a

 //        DictionaryBasedBreakIterator to share a single instance of

 //        BreakDictionary.

 //

 //        TODO:  it'd probably be cleaner to add the reference counting to

 //        BreakDictionary and get rid of this class, but doing it this way

 //        was a convenient transition from earlier code, and time is short...
