/**
 * This file deals with saving data state (appState, elements, images, ...)
 * locally to the browser.
 *
 * Notes:
 *
 * - DataState refers to full state of the app: appState, elements, images,
 *   though some state is saved separately (collab username, library) for one
 *   reason or another. We also save different data to different sotrage
 *   (localStorage, indexedDB).
