title: Changing the default filename when using mPDF
body: <p>I'm currently using <a href="http://www.mpdf1.com/mpdf/index.php" rel="noreferrer">mPDF</a> to generate a pdf from HTML (which was generated by PHP).</p>
  
  <p>All works as expected but I'd like to be able to change the default filename.  Currently, I have:</p>
  
  <pre><code>$payStub=new mPDF();
  $payStub-&gt;SetTitle('My title');
  $payStub-&gt;WriteHTML($pcTableRows);
  $payStub-&gt;Output();
  </code></pre>
  
  <p>When I save the pdf that opened in my browser it defaults to <code>mpdf.pdf</code>.<br>
  Is it possible to change <code>mpdf.pdf</code> to something of my choosing?  </p>
  
  <p>I tried </p>
  
  <pre><code>$payStub-&gt;Output('myFileName.pdf');
  </code></pre>
  
  <p>and</p>
  
  <pre><code>$payStub-&gt;Output('myFileName.pdf', 'F');
  </code></pre>
  
  <p>but those want to save it to the server, I'm trying to have it for when the user saves it locally.</p>
