Slicing and Dicing

The code to take horizontal slices through STL files is coming along.



The picture shows the RepRap GUI with an STL file loaded (this is clearly a silly orientation in which to build this block-like object, but it lets me slice the logo...). Inset is the cross-section generated near the top of the block when the "Produce" button is pressed (the purple rectangles can be ignored - they're for debugging).

At the moment the information is an unstructured list of line segments. Now to add some structure so the extruder can follow it...
