Wattcher, part 2!

OK so I spent some more time cleaning up my code today and have the next part of my “wireless data acquisition and reporting” project done. In this section, I show how to listen and parse XBee packets using python and then graph some useful data to prove that the sensors work. All in 165 lines of code (not including already-written libraries, of course)
