passbook generates both numberStyle and currencyCode on the balance field #38
Description
The passbook library is generating passes that are not loadable by IOS due to the fact that it defaults 'numberStyle' on a the balance header. This is reproduced by explicitly setting the currencyCode as shown in the unit tests in the attached PR.
I submitted pull #37 as a way to reproduce the problem with a possible fix. Thanks for your consideration.
