#### strategy::distance::cross_track_point_box

Strategy functor for distance point to box calculation.

###### Description

Class which calculates the distance of a point to a box, for points and boxes on a sphere or globe

###### Synopsis

    template<typename CalculationType, typename Strategy>
    class strategy::distance::cross_track_point_box
    {
      // ...
    };

###### Template parameter(s)

Parameter | Default | Description
--- | --- | ---
typename CalculationType | void | numeric type for calculation (e.g. high precision); if void then it is extracted automatically from the coordinate type and (if necessary) promoted to floating point
typename Strategy | haversine<double, CalculationType> | underlying point-point distance strategy

###### Constructor(s)

Function | Description | Parameters
--- | --- | ---

|  | typename Strategy::radius_type const &: r:
    cross_track_point_box(Strategy const & s)
|  | Strategy const &: s:

###### Member Function(s)

Function | Description | Parameters | Returns
