 * \brief Bargraph2 Click example
 * 
 * # Description
 * The example starts off with the initalisation and configuration of the logger and Click
 * modules and later on showcases different ways of lighting LED diodes on the Click.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * This function initializes and configures the logger and Click modules.
 * 
 * ## Application Task  
 * This function shows the user how to light single and multiple LED diodes.
