title: How do I programaticly navigate to a route from an event handler in React Router 4.0?
body: <p>I need to navigate to a route after an event is successful.
  This seems to have changed since previous versions.
  Previously we would do this:</p>
  
  <pre><code>import { browserHistory } from 'react-router';
  ...
  handleClick(){
    doSomething();
    browserHistory.push('/some/path');
  }
  </code></pre>
