Tie all point data to consistent geographies of interest

For point data, add variables to associate each data point with geographies of interest: census tract, zip code, city council district, county commission district, State house and senate district.
Some of the files do include some geographies but the specifics seem to vary across the data files - should just be a matter of a nice geocoding script to make all the files interoperable. This would also facilitate the production of reports of key metrics for each geography (profiles of one’s City Council district, etc).
