Estlcam Engrave with finish pass example (v11 CAM)

Example of using Estlcam Engraving to create a bidirectional roughing path and a climb cut finish pass using the point to point tool (manual shape detection, left click to select any point, right to select/set the green line as a path). It's a bit of a hack that is only possible w/ v11. It requires a duplicate tool definition that allows a full depth cut by default. The large finishing allowance was just to make the finishing pass more noticeable in the preview.
