Allow components to register their subComponents.

```js
// List.vue
import ListItem from './ListItem.vue'

export default {
  name: 'List',
  subComponents: {
    Item: ListItem
  }
}
```

## Background

See this issue: [Allow a component to register its own subComponents](https://github.com/vuejs/vue/issues/8249)

## Install

```bash
# Yarn
yarn add vue-component-register

# npm
npm i vue-component-register
```

### CDN

Avaliable as `window.VueComponentRegister`.

`VueComponentRegister` will automatically calls `Vue.use()` if `Vue` is available as a global variable.

## Usage

```js
/* main.js */
import Vue from 'vue'
import ComponentRegister from 'vue-component-register'
import Button from './components' // No subComponents
import List from './components' // Include subComponents: ListItem

Vue.use(ComponentRegister)

Vue.component(Button.name, Button)
Vue.component(List.name, List)


/* App.vue */
import Step from './components' // Include subComponents: StepItem

export default {
  name: 'App',
  // Component-level register
  components: { Step },
  render() {
    return <step>
      <step-item>
        <list>
          <list-item>first step</list-item>
        </list>
      </step-item>
    </step>
  }
}
```
