Title: Add angular momentum ipython notebook example

Here is an ipython example notebook highlighting the use of the quantum angular momentum module. There was also a small issue of CG/Wigner symbols not being commutative. @ellisonbg

A couple points:

* I realized a couple latex characters are no longer rendered correctly, namely `\mathcal{R}` (for Rotation operator) and `\mathcal{C}` (for ComlexSpace). They worked fine when I made my initial quantum printing notebook, but that was 5 months ago. Now they output some Asian language character.

* The notebook currently in the tree is version 2, while the latest ipython master runs the notebook version 3. Since I didn't think to roll back IPython, the version I submitted is version 3. Do we want to stick to one or the other? It might come down to if IPython 0.13 or SymPy 0.7.2 is released first.
