MousePanningExample v1.00
This function offers a simple template that demonstrates custom panning behavior bound to mouse movement. This Fcn doe NOT use the native |pan| function.
Default behavior is to pan the designated axis when the MIDDLE MOUSE button is held and dragged. This can be changed to the LEFT MOUSE or RIGHT MOUSE by simply changing the expected click type in the |startPan| fcn below.

This example was inspired by the excellent |akZoom| fnc written by Alexander Kessel. I've deconstructed it a bit in order to make it easier to incorporate with GUIs that already have actions bound to the 'mouse up' and 'mouse down' callbacks.
