Query with has_available_redemptions?

[sammdec]

Hi there, more of a query than an issue, I have found looking through your code really really helpful and have learnt alot from it, so thank you very much for that!

I noticed one method though and I don't see how it works and was hoping you might be able to shed light on it.

https://github.com/fnando/coupons/blob/master/lib/coupons/models/coupon.rb#L65
The method named has_available_redemptions?, I assume should return true if there is no limit set(0) but from this code it will return false?

Therefore would that not make redeemable? false as well
