title: Get the title of a given figure
body: <p>I have created a figure and have attached to it a title like this:</p>
  
  <pre><code>def func():
      fig = plt.figure()
      fig.suptitle("my title")
      return fig
  </code></pre>
  
  <p>Now I would like to retrieve the title I set in the function. Something like this:</p>
  
  <pre><code>fig.get_title()
  </code></pre>
  
  <p>It seems not to exist. Any idea besides returning the Text object that I can get from the fig.suptitle("w/e") function ?</p>
