            // remaining unswapped entries - including possibly itself.
            // This is really just slightly complicated way of doing a random 'draw',
            // which is exactly what is required to perform a shuffle.

            // produces a deterministic sequence of numbers with statistical properties similar
            // or at best equivalent to random numbers. For 'real' randomness, please turn
            // to System.Security.Cryptography.RNGCryptoServiceProvider.
