Nevermind the errors I mentioned. It was indeed an oversight that was 
cured with a night's sleep (I had my class named Parser, which conflicts 
with the Parser class that antlr uses internally.) Change in names was 
all it needed.

Thanks for the comment on antlrworks and it not running the actions - 
that makes sense as well.
