The documentation says we can use any type when creating a RollingWindow instance, but I am getting the same error with everything I try:

During the algorithm initialization, the following exception has occurred: TypeError : type(s) expected
at Initialize in 57
at __init__ in 68 :: self.window = RollingWindow[tuple](windowLength)
TypeError : type(s) expected

I've tried declaring my own class and using that instead of tuple, I've also tried using dict instead of tuple, always the same error.
