Link to social explorer

[ljwolf]

Would it be possible to add a link to the Social Explorer page? There is a page for each table and variable, and the URLs are pretty clean. Social Explorer doesn’t have all the datasets, it probably has the most popular ones though.

• CBP: https://www.socialexplorer.com/data/CBP2014/metadata/?ds=ORG&var=CBP2014_032_EMP_260_115
• ACS: https://www.socialexplorer.com/data/ACS2016_5yr/metadata/?ds=ACS16_5yr&var=B01001G007

could even use ipython magic to make this display as an iframe in an ipython environment.

For the product module, it might be simple enough to derive the "right" socialexplorer url, and then send the user that way since there will be fewer products. Just from an initial exploration, socialexplorer does not use the same product shortcodes as the Census API.
