pub fn contains<I>(

    point: &<I as IntoIterator>::Item
) -> Option<Tri<<I as IntoIterator>::Item>> where
    I: IntoIterator,
    <I as IntoIterator>::Item: Vertex2d, 

Returns Some with the touched triangle if the given Point is over the polygon described by the given series of points.

This uses the triangles function internally.
