router definition used:

import { router } from '@k-redux-router/react-k-ramel'

const routes = {
  '/': {
    code: 'HOME',
    '/todos': {
      code: 'TODOS',
      '/add': {
        code: 'TODO_ADD',
      },
    },
  },
}

export default router({
  routes,
  state: 'ui.router',
  getState: state => state.ui.router,
})

is there some configuration missing? it would be very nice to fire an action when a route is not found, so that we could add some reaction to redirect to a dedicated 404 page :)
