Z_potts and theta_potts are example objects for mrf2d.
Z_potts is a matrix object containing an observed lattice of a 3 color
(C = 2) Potts model.
theta_potts is the parameter array used to sample it,
it consists of a configuration with one parameter (-1.0) and two relative
positions (to be used with a nearest-neighbor structure).
