Simple test project created with Unity 2020.2.0a15.1993 to test articulations.
Clone repository, open in aforementioned Unity editor.
I need to change the hierarchy of the articulation to be able to add it to another hierarchy as a child. This test
consists of just two ArticulationBodys with a revolute joint. Flipping the hierarchy should ultimately result in an invisible
change to the user by maintaining all position and joint velocities.
