Can't invoke filt(dt=None) on LinearSystem #64

Closed arvoelke closed 7 years ago

arvoelke commented 8 years ago

ValidationError: LinearSystem.default_dt: Unconfigurable parameters have no defaults. Please ensure the value of the parameter is set before trying to access it.

This is because I intentionally don't invoke the superclass of LinearSystem, which is where default_dt gets set (even if it never actually gets used by the underlying filter).
