# Tax calculation is broken out at this level to allow easy integration with 3rd party
# taxation systems. Those systems are usually geared toward calculating all items at once
# rather than one at a time.
#
# To use an alternative tax calculator do this:
# Spree::ReturnAuthorization.reimbursement_tax_calculator = calculator_object
# where `calculator_object` is an object that responds to "call" and accepts a reimbursement object
class ReimbursementTaxCalculator
