FIXED: chromosome crossover issue
FIXED: chromosome crossover issue

This fix includes a bit of last commit. Chromosomes where not swapping correctly because when using rbegin() you must reverse your indexing (subtract the index by the maximum possible index (eg chromosome.size() - 1)). The previous commit had a hard coded value instead of the generic size of the chromosome.
