Adafruit CC3000 Breakout/Shield Simple HTTP Server
See the CC3000 tutorial on Adafruit's learning system
for more information on setting up and using the
CC3000:
http://learn.adafruit.com/adafruit-cc3000-wifi
Requirements:
This sketch requires the Adafruit CC3000 library. You can
download the library from:
https://github.com/adafruit/Adafruit_CC3000_Library
