===============================

.. py:function:: t3toolbox.corewise.corewise_add(X: NDArrayTree, Y: NDArrayTree) -> NDArrayTree

   Add nested objects, X,Y -> X+Y.

   .. rubric:: Examples

   >>> import numpy as np
   >>> import t3toolbox.corewise as cw
   >>> X = (np.ones(3), (1, (), np.ones(2)))
   >>> Y = (2*np.ones(3), (3, (), -np.ones(2)))
   >>> print(cw.corewise_add(X, Y))
   (array([3., 3., 3.]), (4, (), array([0., 0.])))
