示例1: CheckShellNotNested
/// <summary>
/// Check if a shell is incorrectly nested within a polygon. This is the case
/// if the shell is inside the polygon shell, but not inside a polygon hole.
/// (If the shell is inside a polygon hole, the nesting is valid.)
/// The algorithm used relies on the fact that the rings must be properly contained.
/// E.g. they cannot partially overlap (this has been previously checked by
/// <c>CheckRelateConsistency</c>).
/// </summary>

// the interior of the polygon lies on their opposite side
// (on the left, if the hole is oriented CW)
