title: reverse notes order in org mode
body: <p>I make my notes in this order:</p>
  
  <pre><code>* FIRST
  * SECOND
  * THIRD
  ...
  * LAST
  </code></pre>
  
  <p>what I want when I export to html or latex is the reverse order:</p>
  
  <pre><code>* LAST
  ...
  * FIRST
  </code></pre>
  
  <p>so </p>
  
  <ol>
  <li>is there any way or command to reverse the order in org file directly ?</li>
  <li>is there any way to reverse the order while I export the org file to html/latex ?</li>
  </ol>
  
  <p>either should be fine I think.</p>
