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 main.py:line 57
at __init__ in IntrinsicTime.py:line 68 :: self.window = RollingWindow[tuple](windowLength)
TypeError : type(s) expectedI'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.

I get the impression that the type has to be declared in C#, but I don't know how this integration between C# and Python works. Is there a way I can define my own type in this module with my own properties, or will I have to switch to C#?
