Add a Shopping Cart and Checkout Funnel with Snipcart

🚨 Snipcart updated how the script is loaded. Here are the installation docs for more information.

I've also update the code in github to work with Snipcart's latest version.

We want to make sure that when we add something to the cart, we're going to be able to actually add it to our cart. I'm going to be using Snipcart to handle my cart and checkout flow.

We will also our cart update inside of our header with that dynamic value. To do that, we will sign up and install Snipcart where we add the installation to a custom document file and add our class name and data attributes to all of our Add to Cart buttons.

Lastly, we will install the useSnipcart hook so that we can grab that context to show that subtotal anywhere inside of our application.
