Current plan for storing user progress and allowing continuing.  Unfortunately, local storage must be stored on editor rather than in client, as it does not exist within the editor browser. A tutorial can be uniquely identified by its `id` and `version`, which should be sufficient to properly load it. Proposed structure: currentTutorial: `{ id: 'some-id', version: 'some-version' }` progress: `{ 'some-id@some-version': progressObject }` @jensen love to hear your thoughts on this one as well
