Details
If no tsp is given, then the tour length stored in x
as attribute "tour_length" is returned.
If tsp is given then the tour length is recalculated.
If a distance in the tour is infinite, the result is also infinite. If
the tour contains positive and negative infinite distances then the method
returns NA.
