EllipsoidGeodesic

Initializes a geodesic on the ellipsoid connecting the two provided planetodetic points.

Name	Type	Argument	Default	Description
`start`	Cartographic	<optional>	undefined	The initial planetodetic point on the path.
`end`	Cartographic	<optional>	undefined	The final planetodetic point on the path.
`ellipsoid`	Ellipsoid	<optional>	Ellipsoid.WGS84	The ellipsoid on which the geodesic lies.

Cartographic The final planetodetic point on the path.
