/* UI DEV
 *
 * This is a utility module.
 * It initializes a minimalist browserifiable project
 * that contains the Metamask UI, with a mocked state.
 *
 * Includes a state menu for switching between different
 * mocked states, along with query param support,
 * so those states are preserved when live-reloading.
 *
 * This is a convenient way to develop on the UI
 * without having to re-enter your password
 * every time the plugin rebuilds.
 *
 * To use, run `npm run ui`.
