class_docstr: Give a one-liner description/definition of MyManifold.
  
  For example: Class for Euclidean spaces.
  
  Give a more detailed description/definition of MyManifold.
  For example: By definition, a Euclidean space is a vector space of a given
  dimension, equipped with a Euclidean metric.
  
  List the parameters of MyManifold, i.e. the parameters given as inputs
  of the constructor __init__.
  
  For example:
  Parameters
  ----------
  dim : int
      Dimension of the manifold.
code: def __init__(self, dim, another_parameter):
      super().__init__(dim, shape=(dim,), equip=False)
      self.another_parameter = another_parameter

label_desc: Use image node_id 1 to create a new MyManifold object from inherited base classes: Manifold with example: obj = MyManifold(dim, another_parameter)
