The world is grid of cells, with 3 possibilities: Predator(Red), Prey(Green), or Empty(Black).
Both predator and prey have a set health, that changes over time.
The simulation works in steps, with the following rules:
-For prey:
-Tries to move in a random direction.
-Health increases.
-When health reaches a threshold:
-They will reproduce, creating a new "Prey"
-Their health resets to 1
-For predator:
-Tries to move in a random direction.
-Health decreases.
-When health reaches 0, they die and turn into "Nothing".
-If the adjacent square is a prey:
-They will eat it, turning it into a "predator" (reproducing)
-Their health will increase by the amount of health the eaten prey had
