Functions
bool	parse_rgb (const char *value, Color *color)
	parse r,g,b string into Color
void	parse_config_file (Config *config)
	parse configuration file
int	sim_speed_calc (int percent)
	calculate simulation speed based on percentage at 100(%) the usleep time will be 1ms at 1(%) the usleep time will be 100ms
void	color_to_ansi (Color *c)
	convert r,g,c from Color to ansi escape sequence
int	active_rows ()
	if show_stats is true we decrement 1 from rows to make room for stats we do this when iterating through the rows
int	count_neighbors (int x, int y)
	get the neighbors of this cell
void	randomize_matrix ()
	generate cells for new colony
void	restart_simulation ()
	reset history, generation_index and increment restart_index, generate new colony.
