#Google IO Poll Script 
#by: Wes Maag 
#on: 1/21/2011
#
#desc: Just a short script to poll the google-io page for any changes
#the variables from and to should be entered for this to work, you will also
#need to specify what smtp server you want to use if you do not have one set up
#
#I didnt think to add any error handling since i just wanted to get something up quickly
#so you may want to add that if you care to.
#
#Another addition would be to add some sort of keyboard inturrupt that breaks out of the loop
#again I was just lazy and didn't add it because i could always CTRL-C out of it
