Push button about newtonvr

[rustinlee]

The button in the example is done using position constraints on the Rigidbody, which are in worldspace. I've had success managing button position with a Configurable Joint with xyz rotation locked/x and z movement locked with y movement limited, a very low linear limit and a high spring force. This results in something similar to a spring joint but with local space constraints instead of world space. Use code similar to NVR Button to trigger a button press when the button moves too far. This approach works no matter what angle the button is at.

Actually, I lasted tested NVR's buttons on what is now a several weeks old version of the repo, @zite in #28 seems to imply that this might not be the case any more.

Yeah, we're using local constraints now. Should work find on a wall
