Many analysts indicated they wanted to explore farther. We can add a simple drill down by adding an "one homepage in new tab" button under the input fields. Clicking will own the proper site (Twitter or Instagram) on a new tab

Merged PR #25 solves this for current database, but issue left open because graphB side has to parse the name of the collection currently, looking for 'twitter_'. It would be better to not have to check the collection name. Merged for now to get functionality in time for testing. Twitter collections need to start with 'twitter' for now.
