Predator agent design

As the name suggests, the predator agents are carnivorous; they consume the original prey for sustenance. The predators can perform the following actions: do nothing, turn, walk, mate and attack prey. When the predators attack the prey, they inflict damage. When an attacking predator kills the prey it gains a a health bonus, reflecting food consumption. The observations the predators can perform are self age and health examinations, and determining whether any prey or potential mates nearby.
