Triangulate invents faces.

Created by: snovvfall

Ok, this problem makes me crazy. Spent three days trying to solve it with some sort of a workaround, but succeeded only by chance with some meshes. Problem is I cannot import normal mesh with or without triangulate modifier from Blender to Sverchok. In my case I need to import closed ngon consisting of only edges and make it a face right inside Sverchok. But "Fill Holes" returns incorrect result. On the picture below the figure should be with only vertical and horizontal lines, "L"-shaped.
