title: Knockout js loop up to a value
body: <p>I have a integer observable, <code>pages</code>, and I want to loop up to the value of pages in the html eg.</p>
  
  <pre><code>pages = ko.observable(3) 
  </code></pre>
  
  <p>produces</p>
  
  <pre><code>&lt;ul&gt;
  &lt;li&gt;1&lt;/li&gt;
  &lt;li&gt;2&lt;/li&gt;
  &lt;li&gt;3&lt;/li&gt;
  &lt;/ul&gt; 
  </code></pre>
  
  <p>Is there a binding that is suitable for this? </p>
