 * @brief Proximity14 Click example
 *
 * # Description
 * This example showcases the ability of the device to read proximity 
 * value. It can be configured to detect objects up to 20cm of distance.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization of host communication modules (UART, I2C) and 
 * additional pins. Reads device ID and sets default configuration.
 *
 * ## Application Task
 * In span of 100ms reads proximity data from device and logs result.
