title: What does Pylint's "Too few public methods" message mean?
body: <p>I'm running Pylint on some code, and receiving the error &quot;Too few public methods (0/2)&quot;. What does this message mean?</p>
  <p>The <a href="http://docs.pylint.org/features.html#id22" rel="noreferrer">Pylint documentation</a> is not helpful:</p>
  <blockquote>
  <p>Used when a class has too few public methods, so be sure it's really worth it.</p>
  </blockquote>
