 * \brief 7seg Click example
 * 
 * # Description
 * Example code consist of two sections: AppInit and AppTask,
 * and shows number or character on 7seg display.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Application Init performs Logger and Click Initialization.
 * 
 * ## Application Task  
 * Application Task shows functionality of the 7seg Click,
 * shows number or character on left and right display.
