    // type must also be able to create instances of that plugin. For example, a
    // specific instance of a "User login" block, configured with a custom
    // title. To handle plugin instantiation, plugin managers can use one of the
    // factory classes included with the plugin system, or create their own.
    // DefaultFactory is a simple, general purpose factory suitable for
    // many kinds of plugin types. Factories need access to the plugin
    // definitions (e.g., since that's where the plugin's class is specified),
    // so we provide it the discovery object.
