Description

An evolutionary model of grazer behavior.

Grazers have genes for 4 traits:
MaxAngle is the maximum turning angle, MinGrass is the grass threshold to stop grazing and start searching, Investment is the energy invested in offspring, Offspring is the number of offspring.

Colors of grazers are also inherited and mutated, but have no influence on fitness. Grazers can only mate with other grazers with a similar color.
