 Refactor:
 
 Testing:
-- write test to make sure all tax rates are unique per country.
 - write tests for strops.hpp
 - write tests that check error handling for corrupt files. (e.g. references to tax rates, project and cost center that failed to load)
 - peppol testing: add a billing item for each tax category.
