Spatial Justice Test - Uploading CSV bug fixed

You can once again upload a CSV file with latitudes and longitudes to the Spatial Justice Test to analyze how the race and income of people changes at various distances from a set of points.

For instance, you can see how the Top Ten Property Exemptions in Philadelphia are in an area (Center City) where a disproportionate number of Whites and Asians who have an above-median Philly income live. The City is handing out ten year tax exemptions to large corporations to encourage development. Unfortunately our public schools need the taxes now, so this shifts the tax burden to people who are less able to pay.
