Explain a BigCommerce order in plain language

**Objective:** Explain order `{order-id}` in plain language for a support agent.

**Step 1: Read the order**

Call `bigcommerce-get-order` with `id` set to the order id. If nothing returns, say the order was not found and stop.

**Step 2: Read the items**

Call `bigcommerce-get-order-product` with `order-id` set to the order id.

**Step 3: Read the customer**

If `customer-id` is above zero, call `bigcommerce-get-customer` with `id` set to it. Otherwise note it was a guest order.

**Step 4: Report**

* Status, payment status, payment method and dates created, modified and shipped.
* Money: subtotal, tax, shipping, discount, total, refunded amount.
* Items with name, sku, quantity, line total, and any refunded flag.
* Whether `items-shipped` matches `item-count`.
* Anything odd: refund greater than zero, zero shipped items on an old order, discount larger than subtotal.

**Rules & Guidelines:**

* This is a read-only job. Never call any `bigcommerce-*-add`, `bigcommerce-*-update` or `bigcommerce-*-delete` tool. Do not suggest that you changed anything.

**Validation:**

* If a read returns no records, say so plainly and stop; do not invent figures.
* If a result hits the maximum records limit, say the figures may be incomplete and name the filter that would narrow it.
