/**
  A Redux store enhancer that lets you lazy-install reducers after the store
  has booted up. Use this if your application lazy-loads routes that are connected
  to a Redux store.

  Example:

      import { combineReducers } from 'redux';
      import { lazyReducerEnhancer } from 'pwa-helpers/lazy-reducer-enhancer.js';
      import someReducer from './reducers/someReducer.js';

      export const store = createStore(
        (state, action) => state,
        compose(lazyReducerEnhancer(combineReducers))
      );

  Then, in your page/element, you can lazy load a specific reducer with:

      store.addReducers({
        someReducer
      });
