示例1: LocateFromEdge
/// <summary>
/// Locates an edge of a triangle which contains a location
/// specified by a Vertex v.
/// The edge returned has the
/// property that either v is on e, or e is an edge of a triangle containing v.
/// The search starts from startEdge amd proceeds on the general direction of v.
/// </summary>
/// <remarks>
/// This locate algorithm relies on the subdivision being Delaunay. For
/// non-Delaunay subdivisions, this may loop for ever.
/// </remarks>
/// <param name="v">the location to search for</param>
/// <param name="startEdge">an edge of the subdivision to start searching at</param>
/// <returns>a QuadEdge which contains v, or is on the edge of a triangle containing v</returns>
/// <exception cref="LocateFailureException">
/// if the location algorithm fails to converge in a reasonable
/// number of iterations
/// </exception>

* So far it has always been the case that failure to locate indicates an
* invalid subdivision. So just fail completely. (An alternative would be
* to perform an exhaustive search for the containing triangle, but this

* This can also happen if two vertices are located very close together,
* since the orientation predicates may experience precision failures.
