 * \brief Cap Extend 3 Click example
 * 
 * # Description
 * This application features four capacitive sensor pads, 
 * that can sense touch through a variety of different materials.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initialize GPIO Driver
 * 
 * ## Application Task  
 * Depending on which button is touched the usb uart
 * will show number of that button.
