 * @brief Rec N Play 2 Click Example.
 *
 * # Description
 * This example demonstrates the use of Rec N Play 2 Click board by 
 * recording and then playing recorded sound.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver, performs the Click default configuration.
 *
 * ## Application Task
 * Recording sound for 5 seconds, then playing it back.
