Okay, here's the latest version (also posted on the wiki). I have updated all files to the wiki as well. A couple of things that I still need to work on:

1) Better introduction to spin networks/trace diagrams. I don't really say what they are to begin with. I will try to keep this brief.

2) Need to add in a lot of references.

Finally, something for us to think about. Your rank 3 cf's are listed as X(a,b,c,d,i,j) and mine as X(a,b,c,d,e,f). I put in some comments about the relationship between the two forms, and I propose that we use subscripts to separate the two pieces… e.g. yours could be X_{a,b,c,d}^{i,j} since a,b,c,d represent Sym_*(V) but i,j just describe how to pick out some Sym_*(V). Then mine could be just X_{a,b,c,d,e,f} since they all represent explicit Sym_*(V). Let me know what you think. It would be detrimental I think to write everything in terms of your i,j because that is so unnatural for diagrams.

I'd like to give this a few days rest then will hit the whole thing again and figure out the introductory diagram material. I will likely copy/paste most of that so it shouldn't take too long.
