#12414: Geometry azimuth does not compile for geographic coordinates
---------------------------------------+---------------------------
 Reporter:  Ken Barker <ken.barker@…>  |      Owner:  barendgehrels
     Type:  Bugs                       |     Status:  new
Milestone:  To Be Determined           |  Component:  geometry
  Version:  Boost 1.61.0               |   Severity:  Problem
 Keywords:                             |
---------------------------------------+---------------------------
 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.
