Add New Zone Type
Use this button to add new zoneTypes to the list. Must then label them and assign shaders to them. There is no theoretical limit to the number of zoneTypes that you can create, but the more zoneTypes you establish, the less the evolutionary pressure on any single zoneType, and the more effort it will take to get highly tuned results.
When you add a new zoneType, new agents are added to pertain to it. Their settings are taken from the settings for agents of the first zoneType in the list.
