title: Eloquent push() and save() difference
body: <p>I have read laravel 4 docs about eloquent and was quite intrigued by the push() part.
  It says,</p>
  <blockquote>
  <p>Sometimes you may wish to save not only a model, but also all of its relationships. To do so, you may use the push method:</p>
  <p>Saving A Model And Relationships</p>
  <p><code>$user-&gt;push();</code></p>
  </blockquote>

  <p>Sorry but it's a bit blurry on my part the difference between save() and push().
  I am hoping someone can clear this one out for me. Thank you.</p>
