combine Tachyon and Graphics3d objects

[nilesjohnson]

If T is a Tachyon object and P is a Graphics3d object, T + P could return a Tachyon object, or some object subclassed from Tachyon, by extracting the tachyon string of P and combining it with that of T. This would make it possible to convert Graphics3d objects to Tachyon objects by adding them to an empty tachyon scene.
