class_docstr: An abstract base class for a longitudinal data preprocessors
  
  Parameters
  ----------
  n_jobs : `int`, default=-1
      Number of tasks to run in parallel. If set to -1, the number of tasks is
      set to the number of cores.
code: def __init__(self, n_jobs=-1):
      Base.__init__(self)
      self.n_jobs = n_jobs

label_desc: Use image node_id 1 to create a new LongitudinalPreprocessor object from inherited base classes: ABC, Base with example: obj = LongitudinalPreprocessor(n_jobs)
