title: python-docx change 'Authors' meta-data
body: <p>So, I've created a document with python-docx, and everything works as I'd expected, but the 'Authors' are shows as 'Cisco Employee'.</p>
  
  <p>I've tried Googling 'python-docx change author', and other variations, but I can't find anything.</p>
  
  <p>Does an option exist to change the authors name, or is that not possible currently?</p>
