-        Loops through all displayed image stacks and flips the axes
+        This slot flips two of the axes at a time in way that makes it look as though the 
+        stack itself was flipped. 
+        Originally the stack was flipped via the image_stacks.flipAlongAxis method.
+        However, this only flips the volume so points traced on the volume:

+        axis 0: top left
+        axis 1: top right
+        axis 2: bottom left
+
+        The flip buttons should behave as follows:
+        View 1: axis 1 X-axis, axis 2 Y-axis
+        View 2: axis 0 X-axis, axis 2 X-axis
+        View 3: axis 0 Y-axis, axis 1 Y-axis
