Thanks to Taichi's lack of recursion, make tree method really hard to implement.
Currently this example only works on one single CPU thread so don't expect too much on FPS...

Hope this could attract many people in astrophysics. @yuanming-hu Could you update the README.md gallery for this?
I'd like to write a zhihu post on this later when I've time.Done with an English post in: https://forum.taichi.graphics/t/hw-1-2-gravity-simulation-with-tree-method-in-o-n-log-n-2d-3d/980
