You should pass listener to the scanner.

Why do you add errors if you don't use them?

Good point.  Updated to print them out.

LGTM, although this is *not* how we want people to invoke the parser. This works
in the short run, given that not everything has been ported, but eventually we
want people to use the API in AnalysisContext. (It would be nice if that fact
were documented.)

Indeed.  We should talk some about how this should "really look".  Can you point
me to some Java snippets that are closer and that I can use as a good jumping
off point?
