* Bugfixes:   - ParserState::getAb() should return $this->ab, not $ab   - ParserState::closure() and ParserState::reductions() returned an     array of array encapsulated ParserStates.  Array encapsulation is     not only dispensable, but wrong.   - ParserState::shift() and ParserState::reductions(): better     indentation.   - ParserState::reductions(): removed line that gets $ab.  $ab is not     used in this method.
