public class BroadleafRequestedCurrencyDto
The BroadleafCurrencyResolver can be implemented to set the currency (e.g. CurrencyToUse).
This may differ from the currency that was requested (e.g. from the locale, etc.)
By storing the desired currency, we have the opportunity for a later module (like PriceLists) to
check the DesiredCurrency and possibly alter the currency for the request.
