 * \brief CapTouch2 Click example
 * 
 * # Description
 * The demo application shows the button reading and checking.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Configuring clicks and log objects.
 * Reset device and settings the click in the default configuration.
 * 
 * ## Application Task  
 * Calls function to check touch detection (is interrupt occured) and shows message on
 * USB UART on which input touch is detected or on which input touch is released. 
 * Also turns on LED on which linked input interrupt occured.
