Find peak stress on boundary of region(s)
=========================================
This example shows how to sample the stresses around a magnet pocket

It finds the overall region that makes up the magnet pocket (the pocket region
itself and the magnet), and then samples the stresses along the perimeter of
this region.

This script should be run from the scripting tab after the stress calculation
has been run in Motor-CAD.
