class_docstr: Represents a variable-length list of child spaces.
  
  Example:
      self.observation_space = spaces.Repeated(spaces.Box(4,), max_len=10)
          --> from 0 to 10 boxes of shape (4,)
  
  See also: documentation for rllib.models.RepeatedValues, which shows how
      the lists are represented as batched input for ModelV2 classes.
code: def __init__(self, child_space: gym.Space, max_len: int):
      super().__init__()
      self.child_space = child_space
      self.max_len = max_len

label_desc: Use image node_id 1 to create a new Repeated object from inherited base classes: gym with example: obj = Repeated(child_space, max_len)
