Union( <List>, <List> )
Joins the two lists and removes elements that appear multiple times.
Example:
Union( {1, 2, 3, 4, 5}, {3, 2, 1, 7} ) yields {1, 2, 3, 4, 5, 7}.
Union( <Polygon>, <Polygon> )
Finds the union of the two polygons. Works only for where the polygons are not self-intersecting, and where the union is a single polygon.
