title: Generate static docs with swagger
body: <p>Is there a method for creating static documentation for swagger 2.0?
  Perhaps like the 'preview' on editor.swagger.io.</p>
  
  <p>I need to get static html files so I can include them in some static documents.</p>
  
  <p>So far I've not found a way to do this. I see there is swagger-codegens static-docs
  but this only works for swagger &lt;= 1.2.</p>
