title: xtext generate struct of my language when I create file .mydsl in eclipse
body: <p>When I create file with extension .mydsl in eclipse, I need that the created file contains the struct of my language.</p>
  
  <p>For example, the file contains:</p>
  
  <pre><code>use "fileName.mydsl" 
  
  globals {
  
  }
  
  run {
  
  }
  </code></pre>
