The one that turns Price and PriceRange to named tuples

Merge pull request #7 from mirumee/use-namedtuples

Make Price and PriceRange namedtuples

Fixed discounts

This version adds a FixedDiscount price modifier. You can use it to automatically subtract a certain amount from a price.

Price(30, currency='USD') + FixedDiscount(Price(10, currency='USD'))
# Price('20', currency='USD')

We now also have automated testing using Travis and coverage reporting using Coveralls.
