/**
 9-dof unit testing

 The purpose of this program is to demonstrate and calibrate the three
 sensors on teh 9-doft board.

 The first version of this software will test the ITG3200 gyro to find
 the temperature drift line.  Data will be logged to help determine the
 thermal drift line.
 See: http://mbed.org/users/gltest26/code/ITG3200/wiki/Thermal-Drift

 The second versoin of this will test the HMC5883L 3 axis magnometer

 The thrid version tests the ADXL345 library.
