We include diffusion term D Δu =
D ∂2u / ∂x2 to get running waves
∂t u = DΔu + F(u, v) = DΔu +
u(1 - u)(u - a) - v,
∂t v = H(u, v) = ε (bu - v). a

This script uses simple explicit
algorithm. It makes it time steps per frame.
Full ring length is 1024×Δx.
Here we shall test parameters for 2D simulations.
