 * \brief Keylock Click example
 * 
 * # Description
 * This application monitors key position in its lock mechanism.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initialization driver enables GPIO and also writes log.
 * 
 * ## Application Task  
 * Detects the position in which the key currently is.
 * Results are being sent to the Terminal, where you can track changes.
