 * \brief REED Click example
 * 
 * # Description
 * This is a example which demonstrates the use of REED Click board.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init
 * Configuring Clicks and log objects.
 * 
 * ## Application Task
 * Detect the magnetic field near the REED Click.
 * Results are being sent to the Usart Terminal where you can track their changes.
 * All data logs on usb uart when magnetic field is detected.
