示例1: BuildJoinedBasins
/// <summary>
/// Overload of BuildJoinedBasins that takes an outlets shape path used for Inlets resolution. If no outlets/inlets path given, it will treat all points as outlets
/// </summary>
// 2/11/09 rewritten by Chris George to dramatically improve speed:
// (a) use utils.ClipPolygon instead of SpatialOperations.MergeShapes
// (b) create a binary tree modeling the drainage pattern of the subbasins
// (b) merge "upstream-first" using the drainage tree so that each merge combines abutting polygons
