Hide products if there is no inventory

This technique was first used on the TMC sites.

Example: https://casey-veggies.myshopify.com/admin

Benefit: Prevent out of stock items from displaying/populating on the live site

Code:

Open product-loop.liquid

on line 1 before everything add:

{% if product-loop.available == true %}

Then on the last line close the if statement.

{% endif %}
