[antlr-interest] gUnitEditor

I think my first problem was that I was expecting it to compile the grammar
for me as needed.  When it didn't do that, I had ANTLRworks export the .java
files for me, and when that didn't work, I had ANTLRworks compile it for me
(via its automatic support when using its Debug... facilities).
Unfortunately, that puts all the .class files nicely in a 'class'
subdirectory.  Finally, I simply compiled my .java code manually via
commandline, and that seemed to have done the trick, however, it then just
locked up when I pressed run.

At that point I tried just running gUnit on my grammar from the commandline,
and it also hung, so there's either a problem with my grammar, or a problem
with the tests.  I haven't tracked it down any further.  I've just been
using the Debug... functionality of ANTLRworks for testing stuff instead.
