GroveStreams Python 3.2 Hello World 1

#GroveStreams.com Python 3.2 Feed Example
#Demonstrates uploading two stream feeds within a URL and URL
# encoding

#This example uploads two stream feeds, random temperature and humidity
# samples every 10 seconds.
#A full "how to" guide for this example can be found at:
# https://www.grovestreams.com/developers/getting_started_helloworld_python.html
#It relies and the GroveStreams API which can be found here:
