  This example shows the basic settings and functions for retrieving accelerometer
    data. In addition we're setting the data ready signal to interrupt pin one in an
    active high configuration and show additional ways in which the interrupts
    can be configured. 
 
    Please refer to the header file for more possible settings, found here:
