FAYAAAAAAA!!!!!!!!!!!!!!!!!!!

Ok, fire is implemented for the most part. It works pretty well in the
following manner:

We check each turn if spontaneous combustion occurs. If so, the
WildFire class picks a point accordingly and affects the organisms
within it.

A burning point should not have organisms moving into it until the end
of the turn. All vegetation in it is affected by reseting their
reproduction counter so they won’t be able to reproduce. Those who gets
hit by the fire instantly die.

At the end of a turn that fire effected, the burned square should only
contain surviving vegetation. No reproduction, no moving deer.

This works for the most part, but not always. Can’t seem to find this
bug.

Testers/Mark: I have added a Randomizer class (stole it from the foxes
and rabbits project.) it allows us to have once repeatable source.
