OT: GA recipe update

[Sean Ross]

Hi.
For anyone who may have chosen to use my genetic algorithm code from
http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/199121:
I would like to make you aware of the updated version, posted today. Changes
from the previous version include:
    - better integration of roulette selection into the GA framework
    - a bug fix for the previous roulette method
    - removal of dependencies on non-standard library modules (including
Numeric, and my utils module)
    - some re-naming of functions, methods, variables, and a little
re-factoring

The related examples (referenced in the recipe discussion) have been updated
to reflect the changes to this framework.

Thanks for your time,
Sean
