// a different way of generating random values that may "feel" better than true randomness
// every possible value will show up once, but in a random order
// it simply draws from the "bag" every time you get NextValue
// 
// construct either with a list of values, or a size for the most common use
// list values like: new {1, 1, 2, 2, 3, 4};
