[Push] Artificial ant problem

[Pablo Ruggia]

Thanks for your reply
I've done some examples using Java libraries as ECJ and JGAP, and was
interested in developing my own library to learn gp more in detail.
Implementing Push stack based gp seemed very interesting, but if psh is
still in active development I think I can help with that.
I will take a closer look to psh.
Cheers
