title: Jekyll remove first in array?
body: <p>I noticed there is a <code>remove_first</code> function in liquid. Is it possible to use this to remove the first in an array?</p>
  
  <p>For example:</p>
  
  <pre><code>{% animals = 'animals/cat/dog/bird' | split: '/' | remove_first %}
  </code></pre>
  
  <p>The above doesn't work, as it seems you're supposed to pass in a substring, like I am with split.</p>
  
  <p>Is there anyway to do this with Jekyll liquid tags?</p>
