What it does
This configuration class manages the order creditmemo (refund) total collectors in Magento 2.
It determines the order and configuration of how different creditmemo totals (like subtotal, tax, shipping) are calculated and collected.
Developers use this indirectly when working with creditmemo creation, as it ensures totals are processed in the correct sequence.
