Consider storybook for showcase

[itsravenous]

Hi guys,
Just saw this repo had been added and wanted to share something I've used recently for showcasing these sorts of "component libraries". From the Storybook readme, "Storybook is a development environment for UI components. It allows you to browse a component library, view the different states of each component, and interactively develop and test components."

It can "drop-in" to almost any React project and is pretty self-contained. I've used it for rapid UX feedback from stakeholders, but I guess for zooniverse it'd probably be more useful as a simple cataloguing and playground tool.

@itsravenous Thanks for the suggestion. We'll certainly look into it as this repo is still a work in progress.
