The README confused me a bit about how the overlay stuff works (e.g. in the San Francisco example). Is the idea to make a dataframe where every shape is indexed by a pair (base_zone, overlay)? Are you manually making a zone for every possible pair of base_zone and overlay (i.e. a specfile with rows = the cartesian product of Zone X Overlays)? Or do you make one table for base_zone and one for overlay (so rows = Zone + Overlays)?
