Uppy Wizard

[lakesare]

[Slightly edited copypaste from Slack, if you're a transloadit employee please go look at Slack instead, some of the important messages are there]

I think the problem with uppy.io/docs, no matter how we restructure the navigation menu, is that Uppy is a library that doesn't really go well with the list-based documentation. Uppy's structure is tree-like, some options disable some other options.

One way to go about it is to create a choose-your-own-adventure wizard that will be generating Uppy code, similarly to what we do with the Transloadit's Template Wizard. Not only to get people started, I think we can make it so that this is the only thing they'll need for most cases, everything else would be just tinkering with options.

Problems with the current /docs

1. For beginners it's unclear what's the difference between "sources", "uploaders", "companion" and "golden retriever". They all sound like the same thing. I don't think that developers should know all this uppy lore to get up and running.
2. When we look at "User Interfaces" => "Elements", nearly all of these elements are ALREADY in Uppy's Dashboard. The only real choice is whether we want to use "Image Editor", but the developer is required to click through all of these to understand her options.
3. It's not immediately clear that all of the "Sources" listed can only be used with the "Dashboard" UI.

Re:implementation - escodegen + optionally prettier should be good.

From Tim: poor man's version is reusing the checkboxes and the /examples page and conditionally render code underneath there. Would be done a lot quicker, although it would only be for the CDN, not with framework choice.
