- fixed various issues in lisp
- fix more class comments
Breaking change, in the hope that not many external
users are depending on the  reflective facilities:

- iterators are now private, get an iterator over 
  all the reachable parsers using allParser(root)

- transformation methods are not statics in a class
  anymore, but top-level methods
- removed xml_bench.html
- fixed bug in xml_bench.dart
- move CompositeParser2 into its own experimental package
- updated version
