Abstract component identifier. Helpful for picking out a specific child.

  ```js
  class App extends Component {
    render () {
      const title = pick(Title, this.props.children)
      const content = pick(Content, this.props.children)

      return (
        <div>
          {title}
          <ContextView>
            {content}
          </ContextView>
         </div>
     )
    }
  }

  class Title extends ComponentIdentifier { static displayName = 'Title' }
  class Content extends ComponentIdentifier { static displayName = 'Content' }

  ReactDOM.render(
    <App>
      <Title><h2>Hello World!</h2></Title>
      <Content><div>This text gets decorated within `App`.</div></Content>
    </App>,
    document.getElementById('container')
  )
  ```
