<p>This method is a port of the toCoordinateArray() method of JTS. It is not much used as memory management requires us to know wheter we should or not delete the returned object in a consistent way. Our options are: use shared_ptr<Coordinate> or always keep ownerhips of an eventual newly created vector. We opted for the second, so the returned object is a const, to also ensure that returning an internal pointer doesn't make the object mutable.</p>
