this parser is an implementation of earley algorithm
The grammar is programmaticaly generated so you have to write
a parser or something to be able to change easly all the thing. Current setup
generate two parse tree for the next phrase : « la petite ferme le voile </S> ».
Don't mind the </S> but don't forget it as it's the end character.
