* The Honeywell [HMC5883L]
* (http://www.adafruit.com/datasheets/HMC5883L_3-Axis_Digital_Compass_IC.pdf)
* is a 3-axis digital compass. Communication with the HMC5883L is simple and
* all done through an I2C interface. Different breakout boards are available,
* typically a 3V supply is all that is needed to power the sensor.
