add comment tracking to examples

[mdahlhausen]

@mostaphaRoudsari do you think we should add comments to each of the examples? It'll be easy to add a Disqus comment chain to each example.

Hi @mdahlhausen. It's not clear to me how to add it to the page but that would be a huge move forward. How does it work? Are they going to take care of keeping the comments? Will it be different for each page address? I'm asking since Hydra is a single page application. Can we have different discussion/commenting for the same page with different hashes?
I'm going to modify the code to use pushState or location.hash for different users. That might also help for this purpose.

@mostaphaRoudsari . I'll test it out offline before I push it live, but disqus handles comments by the unique url, so I think we'll be fine. I'll work on it later this week.

Nice! I'm working on #2 and #15.

Added comments with this commit. There is a separate comment thread for each example.

@mdahlhausen this is so sweet! Next step will be to write the script to keep track of number of downloads and comments. I can't do it this weekend and next one - working on release and will have a workshop- but then the week after that I will do it.

@mostaphaRoudsari disqus has a post on adding comment counts to a webpage.
