Windup 210: Simplification of Classification and Hint

Not sure if you will like the classification simplification, it is quite hacky.

Both of them are now able to use the "pass variableName from Iteration" simplification.
They are here because of the need for Iteration to pass the iterated variable to the operation. Without this, any operation.and(operation) would not work
