Populate spikes on surface

This effort creates long lines normal to each PopGeo point, then checks to see if each line intersects the brep. If so, that point is ignored, otherwise it gets a “spike”. In this case, I used cylinders instead of spikes but the base plane for each is available if you want to Orient spikes you created in Rhino.
