MeshOverrideStructureof size dl and mesh step dl will not place boundaries on both sides of that structure (i.e. a single mesh step) because of the way theisclosecheck is done. Changed tolerances a bit to fix this as it should be expected behavior.I also added more docstrings explaining how that part of the mesher works. I must admit it's still a bit of a mess, but I don't have time for a complete overhaul (and it's not clear what that might look like).
