BUG:  Two things: 1) I had forgotten the case where a prior probability image is specified for each label whereas I just dealt with the case of a single prior label image.  Both cases are now in the function for calculating the posterior probability image.  2) For the case of a single prior label image, I was changing the value of mu at each iteration without resetting it.  This has now been fixed.
