title: How to display "x-y products of z" in Shopify collections
body: <p>I'd like to be able to display the text "Showing 1-24 of 242 products" (or "Showing 25-48 of 242 products" etc.) on each collection page of a Shopify site.</p>
  
  <p>I thought there'd be a simple bit of Liquid code to do this but either my Google-foo is very weak, or it doesn't exist.</p>
  
  <p>Does anyone have a snippet of code they can share to achieve this?</p>
