EXAMPLES
CREATE TABLE multipolygon (c1 MULTIPOLYGON);
INSERT INTO multipolygon VALUES
(MultiPolygon(
Polygon(LineString(Point(0,0), Point(1,1), Point(2,2), Point(0,0)),
LineString(Point(1,2), Point(2,3), Point(3,4), Point(1,2))),
Polygon(LineString(Point(1,1), Point(2,2), Point(3,3), Point(1,1)),
LineString(Point(2,2), Point(2,3), Point(3,4), Point(2,2)))));
SELECT ST_AsText(c1) FROM multipolygon;
