Create Order
Creates an order.
## Usage notes
* Orders created will be set to incomplete order status.
* You can create as many orders from the same order (cart) as you want.
* Order duplication copies the existing order, assigns a new order number, and sets the new order status to `incomplete`.
* Once the order is paid, the cart is deleted.
* Cart deletion occurs if you are using BigCommerce to accept payments on orders.
