cant seem to get the list of seen animals to the movement strategy it keeps coming up with a null pointer exception.  It's probably something stupid that I messed up.  If either of you can take a look at how I'm using the lists, I think the mistake might be in there, I would greatly appreciate it.

Exception in thread "main" java.lang.NullPointerException
	at AnimalLogic.MovementStrategyHunt.doMovement(MovementStrategyHunt.java:36)
	at AnimalWorld.Main.main(Main.java:94)
