title: Display currency picker in header
body: <p>I'm trying to add currency picker in header of my magento store.
  I have three currencies set and their rates are imported and saved through magentos currency manager. Here is what i've done:</p>
  
  <p><strong>1. Edit page.xml</strong><br>
  I've edited <code>page.xml</code> file and added </p>
  
  <pre><code>&lt;block type="directory/currency" name="currency" as="currency" template="directory/currency.phtml"/&gt;
  </code></pre>
  
  <p>line in <code>header block</code></p>
  
  <p><strong>2. Edit header.phtml</strong><br>
  I've edited <code>header.phtml</code> file and added</p>
  
  <pre><code>&lt;?php echo $this-&gt;getChildHtml('currency') ?&gt;
  </code></pre>
  
  <p>After those two steps, i'm not able to see currency picker in my header. I can display it in i.e. left columnt in content area but never in header. Have you any idea what am i missing ? Thanks in advance.</p>
