 * \brief MpuImu Click example
 * 
 * # Description
 * MPU IMU Click carries the integrated 6-axis motion tracking device 
 * that combines 3-axis gyroscope and accelerometer.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Application Init performs Logger and Click initialization.
 * 
 * ## Application Task  
 * Measured Accel and Gyro coordinates (X,Y,Z) and Temperature in degrees C 
 * are being sent to the UART where you can track their changes. 
 * All data logs on USB UART for every 1 sec.
