 * @brief Charger 26 Click Example.
 *
 * # Description
 * This example demonstrates the use of Charger 26 click board by enabling the device
 * and then reading and displaying the charger status.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and enables the device, sets the output 
 * voltage to 4.2 V and charging current to 100 mA.
 *
 * ## Application Task
 * Tracking charging status, as soon as charging stops, device output is disabled.
