[NEST Users] Retrieving states and parameters variables from NodeCollection

Hey Nest Team,

Calling "NodeCollection.get" returns a dictionary containing the user declared "States" and "Parameters" with other keys such as "global_id", "recordables", and "synaptic_elements". In this context, I want to ask if there is a function in "nest" that returns exactly only the model declared "States" or "Parameters" without having these extra keys, and of course without having a prior knowledge of the "nestml" file from which the model was originated.

Best, Ayssar
