title: Add alias to index from template?
body: <p>How do you add an alias to an index using a template?</p>
  
  <p>If I look at my current templates there are empty sections named aliases in mappings and in the parent of mappings.  I can't seem to find much documentation indicating their use.  What I'm hoping to do is not have to execute an alias add after the index is created.</p>
  
  <p>Thanks,
  Pat</p>
