Scenegraph and Graph Code for FriCAS Program

I created this repository to facilitate discussion of the improvements needed to scenegraph and graph code.

Included here are:

• scene.spad
• graph.spad

For further information see the documentation here:

TODO

1. The code that Franz Lehner sent to me also included isomorphism testing and drawing (using algorithms from Freese's book on "Free Lattices"). I would like to merge this with my code. (it may not all be generalisable to graphs/complexes but parts of it may be and the remainder can still be used for posets).
