 * \brief PowerBank Click example
 * 
 * # Description
 * This application is example of the PowerBank Click functionality
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initalizes I2C driver and makes an initial log.
 * 
 * ## Application Task  
 * This example shows the capabilities of the 
 * PowerBank Click by measuring voltage of the connected
 * battery. In order to get correct calculations user should
 * change "v_ref" value to his own power supply voltage.
