* Use the EOF token provided by the TokenSource (no need to create a new one)
* Fix assigned token index when marks are in place and when add() is called by derived types
* Throw exception for some invalid use of mark/release/seek
* Prevent fill() from adding multiple EOF tokens
* Remove diagnostic println
* Updated field documentation
* Implement getTokenSource
