Using_GeoJSON API.py

#Calling a JSON API
#url to use:   http://python-data.dr-chuck.net/geojson
#This API uses the same parameters (sensor and address) as the Google API.
#This API also has no rate limit so you can test as often as you like. 
#If you visit the URL with no parameters, you get a list of all of the address values which can be used with this API.
#To call the API, you need to provide a sensor=false parameter and the address that you are requesting as the address= parameter that is properly URL encoded using the urllib.urlencode() fuction as shown in http://www.pythonlearn.com/code/geojson.py
