-'''
-    Use a GeoLocation lookup API modelled after the Google API to look up some
-    universities and parse the returned data. The program will prompt for a location,
-    contact a web service and retrieve JSON for the web service and parse that data,
-    and retrieve the first place_id from the JSON. A place ID is a textual identifier
-    that uniquely identifies a place as within Google Maps.
-
-    Use this API endpoint that has a static subset of the Google Data:
-    http://py4e-data.dr-chuck.net/geojson?
