Channel Shuffle operator
This operator divides channels in a tensor of shape :math:`(*, C, H, W)`
into :math:`g` groups and rearranges them as :math:`(*, C/g, g, H, W)`
while keeping the original tensor shape.

Please refer to the paper:
`ShuffleNet: An Extremely Efficient Convolutional Neural Network for
Mobile Devices <https://arxiv.org/abs/1707.01083>`_
by Zhang et. al (2017) for more details.
