Tree only supports up to 3D.

[fulara]

Because 'bounds' has been changed to use array of 3 elements the tree only allows up to 3d.
This is good enough for my requirements. But can be a problem.
The best solution would be to wait for Rust to have support in gnerics for values.

Since I will be using only up to 3 dimension this is not an issue right now. tbf.
On hold.
