Expand description
Coordinate systems, angle units, and reference spheroids.
Mirrors boost/geometry/core/cs.hpp (the cs::cartesian,
cs::spherical, cs::geographic, cs::polar tag templates and their
cs_tag family classifier) together with
boost/geometry/core/coordinate_system.hpp (the
traits::coordinate_system<Point> typedef that picks one of those
tags out per point type) and boost/geometry/srs/spheroid.hpp (the
reference ellipsoid carried alongside any geographic strategy).
Crate split per proposal §3.3: a coordinate system is a type with
an associated CoordinateSystem::Family, and algorithm strategies
bind on the family — never on the concrete CS — so that degree and
radian variants share one impl.
