DrawCalculatorTimelock

The DrawCalculatorTimelock is responsible for pushing Draws to a DrawBuffer and routing claim requests from a PrizeDistributor to a DrawCalculator. The primary objective is to include a "cooldown" period for all new Draws. Allowing the correction of a maliciously set Draw in the unfortunate event an Owner is compromised.
