AD849x breakout board

I've added a small example to the github files. While it's written for teensyduino running on a Teensy 3.0 or 3.1, it shows how easy to use the amplifier is. It should be no problem to port it to other architectures for anyone who has used a microcontroller's ADC before.

I used it to measure the temperature of my laptop's outlet air (57 °C):

A close-up of the connections:

-, Ref, and Gnd are tied together for single supply without any shift in the output. The yellow wire is Out and goes to the Teensy's A0 input, and + is connected to the supply. Simple!
