Pocket & Multiple Islands at different Z Levels

Here's an example which shows a pocketing operation with the boundary and islands defined as individual check-curves. In addition, pocket boundary and islands are located at different Z levels. The boundary location represents the final pocket depth, while each of the islands is at it's own level. In addition this example display a special case with the islands touching the boundary.
