SimilarityFocus Operator.
Generate a similarity focus mask with the same shape of input using the following method:
1. Extract the 3-D matrix(here the first dimension is BatchSize) corresponding
to the axis according to the indexes. For example, if axis=1 and indexes=[a],
it will get the matrix T=X[:, a, :, :]. In this casr, if the shape of input X
is (BatchSize, A, B, C), the shape of matrix T is (BatchSize, B, C).
2. For each index, find the largest numbers in the matrix T, so that the same
row and same column has at most one number(obviously there will be min(B, C)
numbers), and mark the corresponding position of the 3-D similarity focus mask
as 1, otherwise as 0. Do elementwise-or for each index.
3. Broadcast the 3-D similarity focus mask to the same shape of input X.

**SimilarityFocus Operator**
Generate a similarity focus mask with the same shape of input using the following method:
1. Extract the 3-D matrix(here the first dimension is BatchSize) corresponding
to the axis according to the indexes. For example, if axis=1 and indexes=[a],
it will get the matrix T=X[:, a, :, :]. In this casr, if the shape of input X
is (BatchSize, A, B, C), the shape of matrix T is (BatchSize, B, C).
2. For each index, find the largest numbers in the matrix T, so that the same
row and same column has at most one number(obviously there will be min(B, C)
numbers), and mark the corresponding position of the 3-D similarity focus mask
as 1, otherwise as 0. Do elementwise-or for each index.
3. Broadcast the 3-D similarity focus mask to the same shape of input X.
Refer to `Similarity Focus Layer <http://www.aclweb.org/anthology/N16-1108>`_
Args:
input(Variable): The input tensor variable(default float). It should
be a 4-D tensor with shape [BatchSize, A, B, C].
axis(int): Indicating the dimension to be select. It can only be
1, 2, or 3.
indexes(list): indicating the indexes of the selected dimension.
Returns:
Variable: A tensor variable with the same shape and same type
as the input.
Examples:
.. code-block:: python
data = fluid.layers.data(
name='data', shape=[128, 13, 48, 48], dtype='float32')
x = fluid.layers.layer_norm(input=data, axis=1, indexes=[9, 10])
