title: Scala extract neighbours in a List who differ by 1 (Ints)
body: <p>I'm currently trying to extract neighbours in a List who differ by 1. For example if I had my List like this:</p>
  
  <pre><code>List(1,2,3,7,8,10,13,14)
  //By extracting I want to get:
  List(
      List(1,2,3),
      List(7,8),
      List(10),
      List(13,14)
      )
  </code></pre>
  
  <p>I've tried it myself by doing foldLeft, I felt like I was close but yet so far. Can anyone help me? Any suggestions? ^^
  Thank you so much! :)</p>
