 * \brief Microwave2 Click example
 * 
 * # Description
 * This application is an accurate and reliable short to medium range motion detection.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes the click board for communication.
 * 
 * ## Application Task  
 * Data sent from the click board is captured and different actions are applied.
