        double[] fitness​(Organism org,
                         Population pop,
                         GeneticAlgorithm genAlg)
        Calculates the fitness of org. This can be done independently of the Population pop (by ignoring the argument in your implementation) or dependent on the other members of the Population pop. Every implementation of this function should assign the fitness value computed in this function to the given organism. This is important so that the organism knows its current fitness. Note that for simple problems this fitness array will contain only one single value. However, to enable multi-objective fitness functions this has to be an array.
        Parameters:
        org - The Organism to score
        pop - The Population to consider
        genAlg - the parentGeneticAlgorithm
        Returns:
        the fitness score.
