	restructured and its implementation made a little bit more efficient.
	Function choose_out_var() renamed as get_exiting_index(), its signature
	restructured and its implementation heavily changed to (hopefully) made
	it more efficient.
	Function compute_simplex() changed accordingly.
	Function compute_tableau() further simplified by removing a lot of (not
	really necessary) bookkeeping. Local variables renamed for improved
	readability.
