grab BBL numbers from a list of street addresses using the NYC Geo Client API

get-bbls.py

# Read CSV of rent stabilized properties and grab BBL from NYC's GeoClient API
# takes an input CSV file name and output CSV file name as argv
# first two columns of input csv must be address number and address name
# hardcoded for manhattan only, will update in the future 
# run script by doing: python geo-client-api-test.py input.csv output.csv
