\class QGeoRouteSegment
\brief The QGeoRouteSegment class represents a segment of a route.
\inmodule QtLocation
\since 1.1
\ingroup maps-routing
A QGeoRouteSegment instance has information about the physcial layout
of the route segment, the length of the route and estimated time required
to traverse the route segment and an optional QGeoManeuver associated with
the end of the route segment.
QGeoRouteSegment instances can be thought of as edges on a routing
graph, with QGeoManeuver instances as optional labels attached to the
vertices of the graph.
