OBB does not seems to be part of the documentation

[Feirell]

Describe the bug

The OBB class does not seems to be part of the documentation on https://threejs.org/docs. Other classes in the examples directory are part of this documentation.

To Reproduce

Navigate to the https://threejs.org/docs and look for the OBB class.

Expected behavior

It would be nice if the OBB class is part of the official documentation and part of the online docs. This would also help to understand the corresponding example under https://threejs.org/examples/#webgl_math_obb better.
