Ants - Improved

I loved watching the Ants scenario, but it was kind of dull with just Ants and food. Therefore, I have added features to more fully replicate a more complete food chain.

Warning: This can get pretty CPU intensive.

Now there are the following organisms:
Grass - This spreads across the map, and when it dies, it becomes food for the ants.

Ant - These are the center of the simulation, and they bring food back to their anthills. When there is enough food (5) at an anthill, another ant is produced.

Lizard - These are the bane of all ants. They attempt to eat all ants they can, and will reproduce every now and then.

Vulture - These try to keep the lizard population in check, following them until they are ready to eat.
