Methods of payments

[ElenaBelyavskaya]

As a customer buying vouchers/participating in campaigns
I want to be able to select if I pay (a whole voucher price or a part of it) in fiat or smart points
In order to optimize usage of my smart points.

As an SME (platform partner) creating (voucher) campaigns
I want to be able to define

1. Possible methods of payment for the campaign
2. Allowed proportions of payment in fiat/smart points (optional)
   In order to implement my marketing strategy.
