I am trying to find a group associated with https://code.google.com/archive/p/s2-geometry-library/. This is the only post that comes up when searching groups.
My question on the library is, Do the bounding polygons associated with a cell id include the boundaries or sides of the polygon? If so what sides (top, left), (bottom, left)... etc?
