Detailed Description

template<typename Point, typename PointOfSegment = Point, typename CalculationType = void>
class boost::geometry::strategy::within::winding< Point, PointOfSegment, CalculationType >

Within detection using winding rule.

Template Parameters:
PointAny type fulfilling a Point Concept
PointOfSegmentsegment point type
CalculationTypenumeric 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
Author:
Barend Gehrels
Note:
The implementation is inspired by terralib http://www.terralib.org (LGPL)
but totally revised afterwards, especially for cases on segments
Only dependant on "side", -> agnostic, suitable for spherical/latlong
