Example of how `wrappedRef` would relate to `ref` in the case of FluxComponent-wrapped components.

RefExamples.jsx

import React, {Component} form 'react';
import MyComponent from 'my-component.jsx'; // wrapped by FluxComponent

class ParentComponent extends Component {
  componentDidMount() {
    assert(this.fluxComponent.getWrapped() === this.childEl);
  }
  render() {
    return <MyComponent ref={el => this.fluxComponent = el} wrappedRef={el => this.childEl = el} />
  }
}
