class_docstr: Fit method is automatically implemented as changing nothing.
  Please make your steps inherit from NonFittableMixin, when they don't need any fitting.
  Also, make sure that BaseStep is the last step you inherit from.
  Note that we could also define the inverse_transform method in the present object.
code: def transform(self, data_inputs):
      # insert your transform code here
      print("NonFittableStep: I transformed.")
      return data_inputs

label_desc: Use image node_id 2 for calling the NonFittableStep obj's underlying member method code with example usage: obj.transform(data_inputs) and returns: data_inputs
