- Sistemata funzione fitness
- aggiunto vettore per le policy
- (no tested) :D

@TO DO
- sistemare mutazione/crossover, eliminando alleli non validi

@Problemi riscontrati:
l'out of range si riferisce al POP_SIZE =5
STACK TRACE:
	static int POP_SIZE = 5;
	static int APP_SIZE = 2;
	static int PROV_SIZE = 6;
	static int TARGET = 2;
	static int EVOLUTION_SIZE=5;

	fit: Infinity
	####### end best
