      Given a list of string tensors of same shape, performs element-wise
      concatenation of the strings of the same index in all tensors.

        inputs: A list of `tf.Tensor` objects of same size and `tf.string` dtype.
        separator: A string added between each string being joined.
        name: A name for the operation (optional).
  
      Returns:
        A `tf.string` tensor.
