 * \brief 10x10 RGB Click example
 * 
 * # Description
 * This example showcases how to initialize, configure and use the 10x10 RGB Click module. The
 * Click has a 10 by 10 RGB LED matrix which can be programmed to show different colors or even
 * images. LED elements that form the matrix communicate by a single line with the host MCU.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * This function initializes and configures the Click board.
 * 
 * ## Application Task  
 * This function first displays 3 chars { R, G, B }, the string "MIKROE", the company logo and
 * a rainbow in the end.
 * 
 * @note
 * Make sure the logic delays are defined for your system in the c10x10rgb_delays.h file.
