Measuring Terrain

I am sure there are multiple ways to do this.  Here is one possibility.  Instead of deleting the breed just make them a stationary agent with a size of 1 and keep track of them.  If one is created or deleted have a data box reflect that.  Have a 2nd data box that turns the number in the 1st data box into a percentage (there are 10201 total tiles in spaceland).
