Chalktalk 3D Progress

For the past two and a half weeks or so I’ve been implementing features into the MR version of Chalktalk / the Multiuser workstation, including movement of objects out of the boards in z, as well as early implementations of Chalktalk modeler mesh support, thanks to the existence of some C# code written by Gabriel (a graduated NYU MS student who was a major part of FRL and Chalktalk before I ever heard of either of them).
