I am putting the finishing touches on a rudimentary implementation of  
Cartesian Genetic Programming (CGP) for ECJ.  CGP is a genetic  
programming technique invented by Julian Miller - more information  

I am interested in submitting my implementation to the ECJ code base.   
If this is agreeable to you, I was thinking of placing my  
implementation under the "contrib" directory.  My hope is that others  
can improve and build on this work.

I've run a handful of test problems with this CGP implementation: Even- 
n-parity, regression, breast cancer classifier, and the classic Iris  
species classifier.  I would include these as sample implementations  
in the contribution.

Let me know what you think!
