more generic parsing context (will be useful to store packrat data)
packrat parser coded, still needs to be tested.
added the packrat grammar (that parses itself). Actions still to be implemented. Also reworked the cluster layout.
`out` implementation for TRISTATE
lots of bug fixes + first test (does not pass yet)
more bugs fixed. The packrat parser now works!
fix a few debug & logging details. Remaining work: semantics (AST implementation)
fix log
more logs, waiting for actual implementation
packrat parser semantics: WIP
bugfix: cached iterator on linked hashed dictionaries
