title: PyCharm not inserting docstring stub for class?
body: <p>I have the following piece of code:</p>
  
  <pre><code>class Note:
      def __init__(self, note=None, duration=None, start_time=None):
          self.note = note
          self.duration = duration
          self.start_time = start_time
  </code></pre>
  
  <p>I wanted to generate a docstring for the class according to the NumPy docstring style, but it doesn't autocomplete. I have chosen the NumPy format in the settings under <code>File | Settings | Tools | Python Integrated Tools</code></p>
  
  <p>The auto complete works for <code>def __init__()</code>. When I start a new line after it and type <code>'''</code> it automatically inserts this:</p>
  
  <pre><code>'''
  
  Parameters
  ----------
  note :
  duration :
  start_time :
  '''
  </code></pre>
  
  <p>But when I do the same thing under <code>class Note:</code> it doesn't do that. I'm using PyCharm 2017.3.3</p>
