<H1>
<pre>
tsp_tour_len_visitor&lt;Graph, WeightMap, OutputIterator, Length&gt;
</pre>
</H1>

This type is a TSP tour visitor.  It supplies the OutputIterator with the vertices of the tour and
records the total length of the tour.

<h3>Example</h3>

<pre>
double d(0.0);
std::vector&lt;Vertex&gt; c;
boost::metric_tsp_approx
  (g, get(edge_weight, g),
  make_tsp_tour_len_visitor(g, std::back_inserter(c), d, get(edge_weight, g)));
</pre>
