A Vine voucher is really a specific type of FlatRate voucher but because a Vine voucher can be used by mutiple enterprise, it can be considered different enough to warrant it's own class. It still share a lot of the behaviour of a FlatRate voucher, so to avoid duplication, all the shared functionality have been moved to a Vouchers::FlatRatable concern.
