title: In matplotlib, what's the difference between title() and suptitle()?
body: <p>I created 3 subplots using <code>subplot()</code>. Now I'd like to add titles for each subplot. Which one of <code>title()</code> and <code>suptitle()</code> shall I use?</p>
  
  <p>In general, what is the difference between them? Thanks!</p>
