 * @brief 1-Wire Switch Click Example.
 *
 * # Description
 * This library contains API for 1-Wire Switch Click driver. 
 * The library initializes and defines the 1-Wire bus drivers to 
 * write and read data for state programmable I/O, 
 * as well as the default configuration.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs default configuration and sets 
 * the PIO A to OFF and PIO B to ON state.
 *
 * ## Application Task
 * This example demonstrates the use of the 1-Wire Switch Click board by changing the PIO A state, 
 * which is controlling the LED, every time the state of PIO B changes. 
 * Change on the PIO B happens when the button is pushed.
