IsingStateProb

This function returns the likelihood of a single possible state. Is only tractible up to rougly 10 nodes.

Sample states from the Ising model and compute the probability of states. Sampling can be done for any number of nodes, but due to the intractibility of the Ising model the distribution can only be computed up to ~10 nodes.
