Vuex Module 模块化使用

由于使用单一状态树，应用的所有状态会集中到一个比较大的对象。当应用变得非常复杂时，store 对象就有可能变得相当臃肿。

为了解决以上问题，Vuex 允许我们将 store 分割成模块（module）。每个模块拥有自己的 state、mutation、action、getter、甚至是嵌套子模块

src
 ├── store
 │   ├── modules
 │   │   ├── user.js
 │   │   └── login.js
 │   ├── getters.js
 │   └── index.js
 └── main.js

main.js 使用store  import store from "./store";
