Grammar based genetic programming

I've recently rewritten a program I had a while back that used a kind
of grammar based gene along with a "expand this set of productions" to
build a kind of genetic programming system.

This is written in java, underdocumented, and very much experimental. 
If you play with it you're on your own.  Any interesting changes you
make to it though I'd appreciate at least hearing about.

Currently it has several problem domains encoded in it - a "mow the
lawn" problem in which the system tries to learn a set of rules that
allows it to cover a given rectangular area, a user driven "evolve
structures in 3d" that requires POV to run, a user driven "evolve midi
files" and one that builds "plants" (of stems and triangular leaves)
that compete for sunlight (in a small way).
