[Possible Bug] GTournamentSelector #67

Looking at the code of GTournamentSelector, it seems like it is not considering if maximizing or minimizing when selecting from the candidates.

if population.sortType == Consts.sortType["scaled"]:
choosen = max(tournament_pool, key=key_fitness_score)
else:
choosen = max(tournament_pool, key=key_raw_score)

Since in GASimpleGA.py to use elitism it considers the min/max param, it seems like this one should do it as well and use min instead if minimizing.
