title: How to retrieve 2nd level many to many relationship with Eloquent?
body: <p>I describe a possible E-R picture here:
  Entities are : News, Tag, Magazine</p>
  
  <p>A News belongs to many Magazine (Magazine has many news)
  A Tag belongs to many News (News has many tags)</p>
  
  <p>Both are many to many relationships.</p>
  
  <p>Starting from Magazine how would I define models in order to access Tags?</p>
  
  <p>like $magazine->news()->tags(); ?</p>
