Allow proximity to world with nested geometries
Don't emit initial out events [proximity]
Draft Dock

A couple of issues still:
 - Dock movement constraints seem to affect image
 - image jumps when leaving dock
Clear movement constraints when being removed from the dock
Add arm
Clean up taking things off the dock, allow z afterwards.
Constrain dock from moving too far off screen
Attach hands to the camera, yay
Darken the dock, whiten the hand, stagger image z-depths
Add license
Add brief readme
