title: Robot Framework before and after all tests
body: <p>Is there a way to call a Suite Init and Suite Teardown before all tests and after all tests in robot framework.</p>
  
  <p>I have dir structure like</p>
  
  <pre><code>XYZ
       - X1
       - X2
  </code></pre>
  
  <p>I tried writing a <code>__init__.robot</code> in XYZ dir but that didn't help. </p>
