Post Meta Fields from Cost of Shipping

On each of the WooCommerce Orders, there are a couple new meta fields stored in the database:

'_wc_cost_of_shipping' // (value format: Float)

This meta field is associated to the float (read as: decimal) value associated with the cost of shipping

---

'_wc_cos_method'  // (value format: String)

This meta field is associated with the method in which the cost of shipping was stored. Currently, this would be one String of [ manual | shipstation | wc_services ]

---

'_wc_cos_history' // (value format: array of associated arrays, [ [ 'method' => $method, 'cos' => $cost ] ]  )

Introduced in 1.3.0, this meta field stores an Array of historical Cost of Shipping data for this WC_Order. This is only done if the Cost of Shipping has been modified after the first value was saved in order to save one additional database row for each order.
