Initial checkin with basic arduino xbee endpoint firmware working.  BMP085, DHT11, AD7415, Water level analog/detect digital, PIR motion detect sensors are all working with sensor data polled.  Sensor data formatted into small text packets and transmitted to XBee network Coordinator via local XBee Series 2 radio is working.  PogoPlug E02 hosted python xbeenet_server.py script polling coordinator for incoming radio network packets and displaying them to the console is working.  Next steps are to 1) complete firmware files for various hardware configurations (motion detect w/ weather info, water level w/ weather info, etc), 2) Complete sensor data parsing in python xbeenet_server.py script for Pogoplug E02 based server (this script can run on any linux server really), 3) Store sensor data in some format either XML files or MySQL database.
Correct analog pin assignment of of AIN_WATER_LEVEL_ANALOG in the base arduino xbee endpoint ino file.  Copied base code to weather_node and removed missing hardware pieces for that node.

Initial pull from github, which was not empty, was necessary in order to do initial push from local machine.
