class_docstr: Base class to represent the Se2 group.
  
  The SE(2) is the group of rigid body transformations about the origin of two-dimensional Euclidean
  space :math:`R^2` under the operation of composition.

  Example:
      >>> so2 = So2.identity(1)
      >>> t = torch.ones((1, 2))
      >>> se2 = Se2(so2, t)
      >>> se2
      rotation: Parameter containing:
      tensor([1.+0.j], requires_grad=True)
      translation: Parameter containing:
      tensor([[1., 1.]], requires_grad=True)
