 ## TODO
 
-- [ ] fix weird spasming behaviour
-- [ ] improve collision (dont only bounce, maybe follow wall in some conditions etc.)

+- [ ] implement avoidance (point avoidance, edge avoidance)
+	- [ ] implement nodes for these (for 2d, point and a rect node and 3d point and a cube node, circle / sphere too)
+- [ ] implement partitioning (quadtree/octree)
+- [ ] write better usage documentation
