title: Zend_Navigation hierarchy issue with home page
body: <p>I'm building a menu and breadcrumbs with Zend_Navigation but have a small problem with the hierarchy of the <code>home</code> page. Here's a basic example of a Zend_Navigation with an XML file.</p>
  
  <pre><code>&lt;config&gt;
      &lt;nav&gt;
          &lt;home&gt;
              &lt;label&gt;Home&lt;/label&gt;
              &lt;controller&gt;index&lt;/controller&gt;
              &lt;action&gt;index&lt;/action&gt;
          &lt;/home&gt;
  
          &lt;about&gt;
              &lt;label&gt;About&lt;/label&gt;
              &lt;controller&gt;about&lt;/controller&gt;
              &lt;action&gt;index&lt;/action&gt;
          &lt;/about&gt;
  
          &lt;contact&gt;
              &lt;label&gt;Contact&lt;/label&gt;
              &lt;controller&gt;contact&lt;/controller&gt;
              &lt;action&gt;index&lt;/action&gt;
          &lt;/contact&gt;
      &lt;/nav&gt;
  &lt;/config&gt;
  </code></pre>
  
  <p>In the menu, the <code>about</code> and <code>contact</code> page should be on the same level as the <code>home</code> page (as shown below). This works as expected, since all of these pages are on the same level in the navigation XML file.</p>
  
  <pre><code>&lt;ul&gt;
      &lt;li&gt;Home&lt;/li&gt;
      &lt;li&gt;About&lt;/li&gt;
      &lt;li&gt;Contact&lt;/li&gt;
  &lt;/ul&gt;
  </code></pre>
  
  <p>In the breadcrumbs however, the <code>about</code> and <code>contact</code> page should be nested in the <code>home</code> page. This means that the following breadcrumb should be shown on the <code>about</code> page:</p>
  
  <pre><code>Home &gt; About
  </code></pre>
  
  <p>How would I be able to achieve this?</p>
