Spatial Nicholson–Bailey model

Spatial populations dynamics given by the expressions given in The Spatial Dynamics of Host–Parasitoid Systems by H. N. Comins, M. P. Hassell and R. M. May (1992). All examples start with a single patch in the middle with hosts and parasites. Plotted densities are normalised with respect to the most populated patch.
