class_docstr: Compute Y = g(X) = X.
  
  Example Use:
  
  ```python
  # Create the Y=g(X)=X transform which is intended for Tensors with 1 batch
  # ndim and 1 event ndim (i.e., vector of vectors).
  identity = Identity()
  x = [[1., 2],
       [3, 4]]
  x == identity.forward(x) == identity.inverse(x)
  ```
code: def _inverse(self, y):
      return y

label_desc: Use image node_id 6 for calling the Identity obj's underlying member method code with example usage: obj._inverse(y) and returns: y
