public class LinearRing extends LineString
LinearRing.
A LinearRing is a LineString which is both closed and simple.
In other words,
the first and last coordinate in the ring must be equal,
and the interior of the ring must not self-intersect.
Either orientation of the ring is allowed.
A ring must have either 0 or 4 or more points.
The first and last points must be equal (in 2D).
If these conditions are not met, the constructors throw
an IllegalArgumentException
