> GeoPath has the current behavior:
>  * When provided a path with two consecutive identical points: In all cases it generates an {{IllegalArgumentException}} because it tries to build a plane with those two points.
>  * When provided a path with two consecutive numerical identical points: In case of {{GeoStandardPath}} it throws an {{IllegalArgumentException}} because the path is too short. The case of {{GeoDegeneratePath}} is more complicated as it builds the path but the plane can be bogus. In some cases points on the other side of the world can be "In Set".
> I think the factory should filter out these points, in the same way it is done for {{GeoPolygon}}. If this is not the desired behavior then the factory  should throw a consistent {{IllegalArgumentException}} in all cases.
