 * @brief   Testing cute OS.
 * @details	Traffic light system (Chapter 8 - Embedded C by Professor j. Pont). 			
 * 			See \ref traffic.c for the implementation and sequence of the system.
 * @version 1.0.0
 * @date    2022-03-24
 * @copyright Copyright (c) 2022
 * 
 * @details	Application usage:
 * 			- Run the application.
 * 			- The application will run the traffic light system.
 * 			- The system will run in a loop:
 * 				1. Red for some seconds, then
 * 				2. Red-Amber for some seconds, then
 * 				3. Green for some seconds, then
 * 				4. Amberfor some seconds, then
 * 				5. Repeat from step 1.
 * 			The duration of each state is defined in the enum 
 * 			\ref TRAFFIC_SEQUENCE_DURATION_t in \ref traffic_cfg.h file.	
 * 			
 * 			Code explanation:
 * 			1. Initialize the Cute OS.
 *              @code cuteOS_Init();    @endcode
 *          2. Initialize the tasks.
 * 				@code TRAFFIC_Init();	@endcode
 * 				See \ref TRAFFIC_Init() for more details.
 * 			3. Create the tasks.
 *              @code cuteOS_TaskCreate(task1, 1000); // task1 will run every 1 second  @endcode
 *              @code cuteOS_TaskCreate(task2, 2000); // task2 will run every 2 seconds @endcode
 *          4. Start the Cute OS scheduler.
 *              @code cuteOS_Start();   @endcode
