public static interface BSPTree.VanishingCutHandler<S extends Space>

This interface handles the corner cases when an internal node cut sub-hyperplane vanishes.

Such cases happens for example when a cut sub-hyperplane is inserted into another tree (during a merge operation), and is split in several parts, some of which becomes smaller than the tolerance. The corresponding node as then no cut sub-hyperplane anymore, but does have children. This interface specifies how to handle this situation. setting
