Topology documentation uses unexplained concepts

Description
next_left_edge is mentioned a the docs for AddFace and Polygonize in the topology documentation. For instance in https://postgis.net/docs/TopologyPolygonize.html it says "Note: This function does not use nor set the next_left_edge and next_right_edge fields of the edge table."
However there is no documentation of what 'next_left_edge' means and what it does. The user is left without any way of figuring out what the consequences of that note are.

We probably want to add a chapter about the "topology schema". Closest to an explanation is the slide deck http://strk.kbt.io/projects/postgis/Paris2011_TopologyWithPostGIS_2_0.pdf which is linked from https://postgis.net/docs/Topology.html
