Dynamics Retail Discount Interface – IDiscountUsingMarginalValueRanking

We have talked about marginal value ranking algorithm as a backup plan for dynamic programming best deal algorithm. IDiscountUsingMarginalValueRanking is the interface that the discount needs to implement.

        public interface IDiscountUsingMarginalValueRanking
        {
            /// <summary>
            /// Gets the discount deal estimate.
