title: Programmatically navigate using react router V4
body: <p>I have just replaced <code>react-router</code> from v3 to v4.<br>
  But I am not sure how to programmatically navigate in the member function of a <code>Component</code>.
  i.e in <code>handleClick()</code> function I want to navigate to <code>/path/some/where</code> after processing some data.
  I used to do that by:</p>
  
  <pre class="lang-js prettyprint-override"><code>import { browserHistory } from 'react-router'
  browserHistory.push('/path/some/where')
  </code></pre>
  
  <p>But I can't find such interfaces in v4.<br>
  How can I navigate using v4?</p>
