Implementing the development store

We will start with the development store:

1. Create a src/store/ directory, then a src/store/index.dev.js file. Remove all the store-specific logic from the src/index.js file and put it into this file. src/store/index.dev.js should look as follows:

import { createStore, compose } from 'redux'import { persistState } from 'redux-devtools'import appReducer from '../reducers'import DevTools from '../containers/DevTools.jsx'function getSessionKey () {  const matches = window.location.href.match(/[?&]debug=([^&#]+)\b/)  return (matches && matches.length > 0)    ? matches[1]    : null}const enhancer = compose(  DevTools.instrument(),  persistState(getSessionKey()))

2. Then, we will export a configureStore(initialState) function, ...
