+<b>Median filtering boundary values.</b><br>
+June 8, 2011<br>
+Danielle Jorgens, Tom Goddard<br>
+Median filtering puts zeros on the boundary of the volume box. Data from Danielle had 8-bit values
+ranging from 34-241.  The median filtered version adds lots of mysterious 0 values outside the range
+of the original map values.  That seems like an error since the median can't produce a value outside
+the original data range, unless you know about the weird zero filling on the boundary. Would be nice
+to improve the code so it gives the proper median boundary values.  Will require 6 + 12 + 8 cases to
+handle grid points on faces, edges, and corners.
