/* this algorithm will calculate the amount of mutual information between two data sets in their current orientations */

|
/* it is a re-write of the original algorithm for purposes of improved speed. the hope is that it won't affect accuracy. */

/* rather than computing mutual information for the whole volume of data, the algorithm computes it for three orthogonal */
