 * @brief 3DHall8 Click example
 *
 * # Description
 * This application shows capability of 3D Hall 8 Click board. 
 * It configures device and reads sensor data. Sensor is capeable 
 * of reading magnetic flux density from 3 axes and temperature.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization of device communication and application log 
 * and configures device.
 *
 * ## Application Task
 * Reads data from the device and logs it in span of 500ms.
