> Once {{im2col}} and {{pad_image}} are vectorized over all examples, the convolution layer functions can be vectorized as well.  This would result in a single matrix multiply in the forward function that computes the convolution over all {{n}} images at once, rather than using a {{parfor}} loop over the examples.
