 * \brief Key Lock 2 Click example
 * 
 * # Description
 * Keylock 2 Click carries antistatic process sealed keylock mechanism that
 * has three positions.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initialization driver init.
 * 
 * ## Application Task  
 * Checks the current key position and logs the current position on the USB UART.
