feature request. Allow to analyze reexported components

AnyComponent.jsx

import * as React from 'react';

export default class AnyComponent extends React.Component {
    anyMethod(){
       //..
    }
    render(){
       return (<div></div>)
    }
}

Test.jsx

export {AnyComponent} from './AnyComponent';

react-docgen Test.jsx

throws exception "No suitable component definition found"

But should analysis content of AnyComponent.jsx.

What do you think about it?

Start with the reexport example in Test.jsx and the component definition in AnyComponent.jsx, then run the react-docgen command shown in the issue to reproduce the exception. Trace how the CLI handles the reexport and compare it with direct component analysis. Done means Test.jsx is analyzed without the "No suitable component definition found" error and exposes AnyComponent's documentation data.
