title: how to import .refCount() in rxjs / angular
body: <p>I've got <code>angular2-seed</code>-based angular 2 app. I've got following angular/rx code:</p>
  
  <pre><code>this.http.get(...).map((res) =&gt; res.json()).publishReplay().refCount();
  </code></pre>
  
  <p>I use</p>
  
  <pre><code>import { Observable } from 'rxjs/Observable';
  import 'rxjs/add/operator/map';
  import 'rxjs/add/operator/publishreplay';
  </code></pre>
  
  <p>to import all operators separately. But it seems there's no file to import <code>refCount</code> operator... or I am missing something. I'm pretty sure there should be such file, maybe it's stored in a different location.</p>
  
  <p>The brute force solution, the only I've managed to get working, is very brutal:</p>
  
  <pre><code>import 'rxjs';
  </code></pre>
  
  <p>I'm using <code>rxjs</code> v5</p>
