/* MOCK DEV
 *
 * This is a utility module.
 * It initializes a minimalist browserifiable project
 * that contains the Metamask UI, with a local background process.
 *
 * Includes a state reset button for restoring to initial state.
 *
 * This is a convenient way to develop and test the plugin
 * without having to re-open the plugin or even re-build it.
 *
 * To use, run `npm run mock`.
