WC_Abstract_Order::calculate_taxes() public WC 1.0

Calculate taxes for all line items and shipping, and store the totals and tax rows.

If by default the taxes are based on the shipping address and the current order doesn't have any, it would use the billing address rather than using the Shopping base location.

Will use the base country unless customer addresses are set.
