title: Error param type in React app written in Typescript
body: <p>I'm using atom-typescript package and I have made a simple example. Here is it:</p>
  
  <pre><code>import * as React from "react"
  
  interface Props {}
  
  export class HelloWorld extends React.Component&lt;Props, {}&gt; {
    render() {
      return &lt;div&gt;Hello World&lt;/div&gt;;
    }
  }
  </code></pre>
  
  <hr>
  
  <pre><code>import * as React from "react"
  
  import * as HelloWorld from "./components/HelloWorld"
  
  React.render(
    React.createElement(HelloWorld, null),
    document.getElementById('app')
  );
  </code></pre>
  
  <p>The problem is that I get this error:</p>
  
  <pre><code>at line 6, file /Users/mazzy/vagrant-devbox/expressjs-typescript/app/app.tsx Argument of type 'typeof "/Users/mazzy/vagrant-devbox/expressjs-typescript/app/components/HelloWorld"' is not assignable to parameter of type 'ComponentClass&lt;any&gt;'.
  </code></pre>
  
  <p>Obviously I have installed <code>react.d.ts</code> file. Have any idea about this?</p>
