Changes the random object's seed value to start a new sequence of pseudo random numbers.
You might use this when you want to re-initialize a Random object but don't want to create an entirely new one. If you are creating multiple sequences, this helps to make the sequences unrelated to one another.
This example assumes that the method created a sequence from an earlier seed.
