Version 1.0.7

Changes:

1. There are no longer invisible bounds to the level - if a Creature leaves the simulation's bounds, they will wrap around and come out the other side! 

2. The generation killers have been recolored.

3. Every creature keeps a log of the creatures they currently see as a list. Previously, when they would change the creature they were paying attention to, they would pick a RANDOM element from said list. Now, they pick the NEXT occurrence from the list and move it to the back, i.e. pay attention to every creature sequentially.

Enjoy!
