[galib] Change mutation function

[Mark Hodgson]

Hi all,

I'm having problems changing the mutation function during an evolution.
GAGenome provides methods to change crossover and objective functions, 
both of which are working fine. However it does not have a method to 
change the mutation function so I am trying to use the

mutator(GAGenome::Mutator)

function of GAGenome to change it. This is not working; the previous 
mutation function continues to be used.

Am I missing something obvious? Is there a way to change the mutation 
function mid evolution?

Thanks,

Mark Hodgson
