  1. or download this
    has_a_cycle
    
    ...
        Returns a cycle if the graph has one (as a list of vertices), an e
    +mpty list if no cycle can be found.
    
        Note that this just returns the vertices of a cycle: not any parti
    +cular cycle, just the first one it finds. A repeated call might find 
    +the same cycle, or it might find a different one, and you cannot call
    + this repeatedly to find all the cycles.
