7	* Compatibility with WooCommerce Mix and Match Products.
8	*
9	* Container lines are never re-priced by tiered pricing: the Mix and Match plugin owns the
10	* container's price, and re-pricing it would charge the tier price on top of the contents.
11	*
12	* Child items (the products inside a container) are excluded by default. The "Apply tiered pricing
13	* inside containers" setting lets tiered pricing discount them — only for containers with per-item
14	* pricing, where every child line carries its own real price. Children of statically priced
15	* containers always stay untouched.
