Determines a List of GeoPoint elements which create the Polygon.

Coordinates of the Polygon need to be given in the counter-clockwise order. You need to provide at least 3 coordinates for open polygons and 4 coordinates for closed polygons. We consider a Polygon open when the start and end vertices are different and similarly we consider a closed polygon, that has the start and end in the same GeoPoint. Both types are correct. None of Coordinates can be within an area that extends up to 5 latitude degrees around the poles.
