How to calculate and interpolate daily averages for a given location using Safecast data.

When running this script make sure your browser's default download folder is the same in which the script is running. Also, in the same folder, include a file called FukushimaCensus.csv containing list of whatever times and locations you'd want to generate these interpolated values for. A sample version of FukushimaCensus.csv is attached here.
Run this interpolation script. The script assumes an exponential decay model, and fits a predictive curve using daily averages taken from within 100m of a given site. The script also generates a csv file containing the daily mean radioactivity within 100m of the selection site as well as the standard deviation on the mean.
