Explore Iodide integration

[openjck]

We have been talking about integration with Iodide for a while. I'd like to prototype some some ideas to see how they are received.

My first idea is to have an Explore with Iodide button next to each chart. Clicking it could populate an Iodide project with all of the data in all facets already pulled in, and with a basic chart visualization setup using the same graphing library that we use on Ensemble. The user could then play around with the data, share their visualizations, and invite others to fork and improve their visualizations. They could come up with some clever visualizations that we never considered.
