title: How to create a case insensitive map in Go?
body: <p>I want to have a key insensitive string as key. 
  Is it supported by the language or do I have to create it myself?
  thank you</p>
  
  <p><strong>Edit:</strong> What I am looking for is a way to make it by default instead of having to remember to convert the keys every time I use the map.</p>
