Issues with CANNON and this.physics

[ckasarda]

When downloading the repository and running the examples, I run into an issue where this.physics is undefined in the hand-body.js script. Also, I have learned recently that CANNON physics engine no longer works with A-Frame. I was wondering if we could implement a version that uses AMMO instead? Ammo.js is still compatible withA-Frame and aframe-physics-system. Thank you!
