Hurrah!  The PEG parser can indeed be used to make parse trees; it's just
that Robin, who's doing the work, doesn't have sufficient Java chops
at present.  But I can't believe it's a big deal.

Very cool.  We may not be smart enough to do this yet in full generality,
but look at Nick's Prolog version.

We'll make it happen.
