Modify Directed info to use the causal entropy rate #22

Directed information, as is normally written in papers, is described in terms of a cumulative conditional mutual information on an incoming stream of data. I've modified it here to use an n-order markov model of the time series, so that we can actually compute it in reasonable time with the JIDT estimators.
