    ROTATION WITH QUATERNIONS AND FLYING

This project demonstrates the use of quaternions to rotate objects and fly them

The Main tab only contains code to help you choose from a number of demo projects. You will not need it in
your own projects.

--# Notes
--[[
This set of demos is aimed at people who have not worked with 3D before.

3D is a very, very big subject, with a lot to learn, so this set of demos can only scratch the surface, and cannot possibly explain everything there is to know.

You can simply watch the demos to see what Codea can do, but ideally,you should read up on 3D before trying to understand how the demos work, and before trying your own projects.

Also, this is not a set of "Wow, look what 3D can do" demos. If you look at them all without reading the notes,
