Upgrade project's visual impact with ring of red LEDs, SN74HC595 and ATmega328P

/*!
 * \file 
 * \brief LedringR Click example
 * 
 * # Description
 * LED ring  R Click is a mikroBUS™ add-on board with a ring of 32 red LEDs driven.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes SPI driver and performs device configuration.
 * 
 * ## Application Task  
 * Show functionality of Led_Ring_R Click, rotating and turn on/off led's, using the SPI interface.
