** \brief An ANTLR3 bounded token factory.
**
** An ANTLR3 bounded token factory. The factory has a fixed number of
** tokens that are re-used as parsing proceeds. Only use this factory
** if you *know* that the number of active tokens will be bounded
** (e.g., if you're using a bounded token stream).
