12414	Geometry azimuth does not compile for geographic coordinates	Ken Barker <ken.barker@…>	Barend Gehrels	"Calling `azimuth` to find the relative bearing of one point to another in geographic coordinates does not compile, e.g.:
{{{
    typedef boost::geometry::cs::geographic<boost::geometry::radian> Wgs84Coords;
    typedef boost::geometry::model::point<double, 2, Wgs84Coords> GeographicPoint;
    typedef boost::geometry::srs::spheroid<double> SpheroidType;

    double azimuth(GeographicPoint boost_a, GeographicPoint boost_b)
    {
      return boost::geometry::detail::azimuth<double>(boost_a, boost_b);
    }
}}}
or 
{{{
    double wgs84_azimuth(GeographicPoint boost_a, GeographicPoint boost_b)
    {
      SpheroidType spheriod(wgs84::a, wgs84::b);
      return boost::geometry::detail::azimuth<double>(boost_a, boost_b, spheriod);
    }
}}}

The problem seems to be caused on line 52 of `azimuth.hpp` in geometry/algorithms/detail, it is:
{{{
    return geometry::detail::vincenty_inverse<ReturnType, false, true>
}}}
when it should be:
{{{
    return geometry::detail::vincenty_inverse<ReturnType, false, true>::apply
}}}
The amended line compiles and gives reasonable results."	Bugs	closed	Boost 1.62.0	geometry	Boost 1.61.0	Problem	fixed
