 * Provides an access control handler for price list items.
 *
 * Price list items are always managed in the scope of their parent
 * (the price list), so they have a simplified permission set, and rely on
 * parent access when possible:
 * - A price list item can be viewed if the parent price list can be viewed.
 * - A price list item can be created, updated or deleted if the user has the
 *   "manage $bundle price_list" permission.
 *
 * The "administer commerce_pricelist" permission is also respected.
