title: possible to use YARD to document erb templates
body: <p>Is it possible to use YARD to document templates or does it require classes in files? I have tried running</p>
  
  <p>yard doc controllers/ models/ views/index/ </p>
  
  <p>but the index views aren't picked up. I see the meta data to be added to extra files in the docs but obviously don't want to render the yard comments. I just want to document the partials used in each view.</p>
  
  <p>thx</p>
