A Softmax layer in a network definition.
This layer applies a per-channel softmax to its input.
The output size is the same as the input size.

Set the axis along which softmax is computed. Currently, only one axis can be set.
The axis is specified by setting the bit corresponding to the axis, after excluding the batch dimension, to 1. Let's say we have an NCHW tensor as input (three non-batch dimensions). Bit 0 corresponds to the C dimension boolean. Bit 1 corresponds to the H dimension boolean. Bit 2 corresponds to the W dimension boolean. For example, to perform softmax on axis R of a NPQRCHW input, set bit 2.
By default, softmax is performed on the axis which is the number of non-batch axes minus three. It is 0 if there are fewer than 3 non-batch axes. For example, if the input is NCHW, the default axis is C. If the input is NHW, then the default axis is H.
