-/* Functions for converting between Cartesian, polar, cylindrical and
- * spherical coordinates.
- *
- * The 3D conversion functions take an integer axis index argument. For
- * cylindrical coordinates this determines the axis of the cylinder, and for
- * spherical it determines which cardinal axis is normal to the azimuth plane.
- *
- * For spherical coordinates the option of whether to treat phi as latitude
- * or colatitude is also available. The 'type' argument takes either of the
- * enumerants cml::latitude and cml::colatitude to reflect this.
