  Fixed row breaker.
  Entire docblock missing.
  Typo.
  * While updating RWC-330, RWC-76 was included. * Fees will only be supported in non RCO mode due to how RCO works as we very much have to create the RCO iframe before the woocommerce handlers. * getAnnuityFactors can now be chosen to display or return. See RWC-331. It can also be chosen to show product price or a custom price. * Added getResursMethodFromPrefix() to make sure we can store payment method data in an early state for the session (for fee handling mostly) * Added internal_tax setting for the fee handling. See RWC-318. This is the way we apply tax classes to the fee. * Some slugs for language fixed. * setFee changed @since because it has been activated.
  Initiated RWC-330, but since we're not allowed to use HTML as is, this has been prioritized down.
