For this 'Table of Content' extension I just need to load it with
`IPython.load_extensions('toc')`

https://github.com/minrk/ipython_extensions/blob/master/nbextensions/toc.js#L125

I see that he also has the IPython.event in here but I don't really
understand what he is doing. Does this define IPython.toolbar if it is
undefined and then calls `toc_button` again afterwards?

Any explanation for what he is defining in L17 would also be nice.

Sorry if these questions are dump. I've never used javascript before.
