Wishlist: Separate the toys in the Sandbox

[Stephanie Leary]

The Sandbox is a good place to see how different UI components will look, but it is not very effective as a teaching tool for those new to Evergreen. Because all the components are jumbled together on one screen, it is hard to which imported modules and data objects are relevant to each one. It would be more helpful if each component were on its own page.

While we could set up individual routes and manually create an index, Storybook would handle that for us, and also provides some scaffolding for documentation and automated testing.
