[galib] multi-objective extension to GALib

[GAAL, Balazs]

We have created an extension which sits on top of GALib and provides 
multi-objective optimization functionality.
Three popular algorithms (NSGA2, SPEA2 and MicroGA) have been implemented.

Drop me a mail if you are intrested in the source code.
We intend to make a website for this extension and some documentation too.
At the moment, all I can provide you is the code with minimal documentation.

Kind regards!
