Function File: narysource (probability_dist,n_order)
This function creates a N-ary order source using the given probability_dist (as a column vector) of a 1-order source building a probability distribution of size len(probability_dist)^order. Basically if you have X-symbol distribution with a N-ary source then we have, in the resultant N-ary source with a X^N symbols. The function is equivalent to the definitions of a q-ary order source.
