Indicates whether the input edges provided to S2Builder are directed or
undirected. Directed edges should be used whenever possible (see
S2Builder::EdgeType for details).
If the input edges are directed, they should be oriented so that the
polygon interior is to the left of all edges. This means that for a
polygon with holes, the outer loops ("shells") should be directed
counter-clockwise while the inner loops ("holes") should be directed
clockwise. Note that S2Builder::AddPolygon() does this automatically.
