FeesItemProcessor determines what tier the account for each transaction has been calculated to be.
From there, it calls the appropriate method to calculate the price. To configure this ItemProcessor, you
use virtually the same configuration you did for pricingTiersItemProcessor . Listing 10-39 has the
configuration for feesItemProcessor .
