    \class QGeoManeuver
    \inmodule QtLocation
    \ingroup QtLocation-routing
    \since 5.6

    \brief The QGeoManeuver class represents the information relevant to the
    point at which two QGeoRouteSegments meet.

    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.

    The most interesting information help in a QGeoManeuver instance is
    normally the textual navigation to provide and the position at which to
    provide it, accessible by instructionText() and position() respectively.

    It is also possible to determine if a routing waypoint has been passed by
    checking if waypoint() returns a valid QGeoCoordinate.
*/

/*!
\enum QGeoManeuver::InstructionDirection

Describes the change in direction associated with the instruction text
that is associated with a QGeoManaeuver.

\value NoDirection
There is no direction associated with the instruction text.

\value DirectionForward
The instruction indicates that the direction of travel does not need to change.

\value DirectionBearRight
The instruction indicates that the direction of travel should bear to the right.

\value DirectionLightRight
The instruction indicates that a light turn to the right is required.

\value DirectionRight
The instruction indicates that a turn to the right is required.

\value DirectionHardRight
The instruction indicates that a hard turn to the right is required.

\value DirectionUTurnRight
The instruction indicates that a u-turn to the right is required.

\value DirectionUTurnLeft
The instruction indicates that a u-turn to the left is required.

\value DirectionHardLeft
The instruction indicates that a hard turn to the left is required.

\value DirectionLeft
The instruction indicates that a turn to the left is required.

\value DirectionLightLeft
The instruction indicates that a light turn to the left is required.

\value DirectionBearLeft
The instruction indicates that the direction of travel should bear to the left.
