Returns a list of station names the train will pass between the selected

+=item $result->route_interesting([I<max>])
+
+Returns a list of (at most I<max>) interesting stations the train will pass on
+its journey. This is somewhat tricky (and therefore experimental).
+
+The first element of the list is always the train's next stop. The following
+elements contain as many main stations as possible, but there may also be
+smaller stations if not enough main stations are available.
+
+Note that all main stations will be stripped of their "Hbf" suffix.

=item $result->route_raw
Returns the raw string used to create the route array.
