I'm going to use a nested GA inside my GP run. So to evaluate my GP
programs, I'm first going to run a small GA run on a some extra data
to be able to evaluate the individuals.
My question is what would be the easiest way to call ECJ with the
lowest overhead possible.

I've been looking at the Console app which starts ECJ itself, but it's
all so correlated to the gui, it is impossible to use the code there.
I will be using the parameter database to pass data to the inner GA
but I haven't decided how to pass data back.

Some hints would be appreciated!
