Algorithm::Evolutionary::Hash_Wheel - Random selector of things depending on probabilities
my $wheel = new Algorithm::Evolutionary::Hash_Wheel( \%probs ); print $wheel->spin(); #Returns an element according to probabilities;
Creates a "roulette wheel" for spinning and selecting stuff. It will be used in several places; mainly in the Algorithm::Evolutionary::Op::CanonicalGA. It's similar to Algorithm::Evolutionary::Wheel, but with a hash instead of an array. Probably should unify both..
new( $probabilities_hashref )
Creates a new roulette wheel. Takes a hashref, which uses as keys the objects to be returned by the roulette wheel, and as values the ones that are going to be used
Returns a single individual whose probability is related to its fitness TODO: should return many, probably
