Modified files: src : simplex.cc

Log message: No longer using (and thus eliminated) functions insert_row_in_matrix(), add_element_to_row(), copy_column(). Function check_optimality() renamed as get_entering_index(), its signature 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.
