A use case, for greater than two parents during crossover would be the [Three 
parent 
crossover|http://en.wikipedia.org/wiki/Crossover_(genetic_algorithm)#Three_parent_crossover]
 described on wikipedia. However, I don't believe that is a common use case, so 
I've reworked my patch to only allow for 2 parent crossover. I have however 
kept the change to the SelectionPolicy API, my thinking is that allowing a 
larger pool of potential parents allow for more diversity.

AS it is currently written SelectionPolicy's and CrossoverPolicy's only work on 
ChromosomePairs, this is severely limiting a users ability to extends their 
functionality.
