LSM303AGR Compass Example with calibration and z-axis

	/*
	* LSM303AGR Compass Example
	*
	* From what I can gather, this shows the proper way to get a compas heading from the LSM303.
	* It solves two problems which aren't addressed in the Adafruit example code:
	* 1.) Show how to incorporate min and max values from calibration. Makes a HUGE difference in my testing.
	* 2.) Take the z-axis into account.
	*
	* Based heavily off Adafruit example code and https://github.com/pololu/lsm303-arduino.
