> Currently, our {{util::pad_image}} function performs zero-padding, which is correct for operations such as convolution.  In some cases, such as max pooling, it is necessary to pad with a different value such as negative infinity.  Therefore, we should extend our {{util::pad_image}} function to accept a {{pad_value}} parameter with a noted typical value of 0.
