 * \brief Accel3 Click example
 * 
 * # Description
 * Accel 3 Click represent 3-axis linear accelerometer.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Application Init performs Logger and Click initialization.
 * 
 * ## Application Task  
 * This is an example which demonstrates the usage of Accel 3 Click board.
 * Measured coordinates (X,Y,Z) are being sent to the UART where you can 
 * track their changes. All data logs on USB UART for every 1 sec.
