Cycle through a list of values

Use ListRotationCycle to loop through a list of values. Once you get to the end of the list, you go back to the beginning.

ListRotationCycle is implemented as a Singleton Pattern. You always just get 1 the very same Cycle object even if you use the new method several times. This is done by using Memoize on the new method. It returns the same object for every use of new that comes with the same List of parameters.
