[antlr-interest] nesting rules, getting rule text

[mzukowski at yci.com]

Yeah, it seems people need a guide to reading the code sometimes.  This
stuff is in Ter's lectures, but maybe something that pointed out techniques
used in the examples would be helpful too for those of you who just start
hacking away?

Great Monty, thanks - these little tips of yours are really helpful to those
of us running blind here : ). I will structure things that way then...
