Integrate visualization into gensim

[piskvorky]

Explore the interface of pyLDAviz. Add direct support for visualizing models, or for export to pyLDAviz.

Tested pyLDAvis with gensim. 20newsgroups working fine. Will test it out on other data sets.

Great! Can you commit an ipython notebook that demonstrates your experiment(s)?

That way, we can discuss your results directly.

@piskvorky Is the original Pyldavis ipynb good enough? it uses gensim

If the support in pyLDAviz is working, I suppose nothing else is needed from gensim's side.

I forgot what the issues there were, maybe there weren't any and this was just a confirmation experiment.
