Energize your single-cell Li-Ion battery with RT9532 and ATmega328P

/*!
 * \file 
 * \brief Charger 13 Click example
 * 
 * # Description
 * This demo application charges the battery.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initialization device.
 * 
 * ## Application Task  
 * This is an example which demonstrates the use of Charger 13 Click board.
 * This example shows the automatic control of the Charger 13 Click,
 * waits for valid user input and executes functions based on a set of valid commands
 * and check the battery charge status.
 * Results are being sent to the Usart Terminal where you can track their changes.
 * All data logs on usb uart for approximately every 1 sec when the data value changes.
