	Implementation:
	1- Creating a Window
	2- read a given map
	3-learn about Bresenham Algo
	4-handling Events
	5-learn about isometric projection
	
	MAIN:
		HANDLING ERROR and GET MAP:
			check arguments.
			read map.
			check map.
			return (map)
		INQUIRE MAP:
			return (col_n & row_n).
		DISPLAY:
			get cordinates.
			convert cordinates from cartesian to isometric
			while drawing the line we should multiply x and y by a unit so that 
			we get dynamic display. In addition, ...
			Thinking=> defining the origin of the plane and the units simultaneously
		HANDLING EVENTS:
			handle ESC
			handle Red Cross


			H : 1920
			W : 1080


	ABOUT THE MLX:
		- mlx_init() establishes a connection to the correct graphical system and 
		will return a void* which
		holds the location of our current MLX instance.
		- mlx_new_window() will return a pointer to the window we just created.
		- mlx_loop() will initiate the window rendering.
