-//    rule. That means moves with the fewest legal onward moves 
-//    should come first.

-//(7) Complete the function that searches for a single *closed* 
-//    tour using the ordered_moves function from (6). This

-//    version of the function will be called with dimensions of 
-//    up to 30 * 30.
