Spike 5000 queries round deux

[epugh]

Description

Demonstrate running 5000 queries in a background process, storing the results in a Snapshot.

Ideally, we run the 5000 queries, building the snapshot. We then make the front end interact as if it was a CSV Upload of data. If that works, great. If it still doesn't scale, then we have a seperate UI. And we figure out how to run not just A scorer, but lots of scorers, and store them..

Motivation and Context

We need moar data! This replaces an earlier attempt, #976 that kept the AngularJS app as the runner for Javascript. It just didn't work... Headless app wasn't the right way to go.
