    \brief The QGeoRouteSegment class represents a segment of a route.
 
    A QGeoRouteSegment instance has information about the physical 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 beginning 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.

    \brief The routeSegment type represents a segment of a Route.
 
    A routeSegment instance has information about the physical layout
    of the route segment, the length of the route and estimated time required
    to traverse the route segment and optional \l {routeManeuver}s associated with
    the end of the route segment.
 
    Instances of routeSegment can be thought of as edges on a routing
    graph, with routeManeuver instances as optional labels attached to the
    vertices of the graph.
 
    The primary means of acquiring Route objects is via Routes via \l RouteModel.
