/**
* \brief Padding zeros to input according to the specify dimension.
* The struct pad_ contains the padding size in each dimension.
* The input and output is a 4D tensor. In PadFunc, we only
* pad zeros to the 2nd to 4th dimension.
*
* Argument in this Function:
* \param pad_ A struct object contains the padding size in each dimension.
* It has six integers. The channelStart and channelEnd indicates
* how many zeros to add before and after the input in channel
* dimension. And the heightStart and heightEnd indicates padding
* in height dimension. The widthStart and widthEnd indicates the
* padding in width dimension.
* \param inputs A 4D tensor, only one input.
* \param outputs A 4D tensor, the output value after padding.
*
* For example,
* Input(2,2,2,3) = [
* [ [[1,2,3], [3,4,5]],
* [[2,3,5], [1,6,7]] ],
* [ [[4,3,1], [1,8,7]],
* [[3,8,9], [2,3,5]] ]
* ] # the shape is (1,2,2,3)
*
* pad_: if channelStart = channelEnd = 1, others are 0.
* Output(2,4,2,3) = [
* [ [[0,0,0], [0,0,0]],
* [[1,2,3], [3,4,5]],
* [[2,3,5], [1,6,7]],
* [[0,0,0], [0,0,0]] ],
* [ [[0,0,0], [0,0,0]],
* [[4,3,1], [1,8,7]],
* [[3,8,9], [2,3,5]],
* [[0,0,0], [0,0,0]] ]
* ] # the shape is (2,4,2,3)
*
* pad_: if widthStart = 1, widthEnd = 2, others are 0.
* Output(2,2,2,6) = [
* [ [[0,1,2,3,0,0], [0,3,4,5,0,0]],
* [[0,2,3,5,0,0], [0,1,6,7,0,0]] ],
* [ [[0,4,3,1,0,0], [0,1,8,7,0,0]],
* [[0,3,8,9,0,0], [0,2,3,5,0,0]] ],
* ] # the shape is (2,2,2,6)
*
* pad_: if heightStart = 1, heightEnd = 1, others are 0.
* Output(2,2,4,3) = [
