> We should add new {{predict_class}} and {{predict_class2d}} utility functions (in {{nn/util.dml}}) that accept a matrix {{X}} and return a matrix {{out}} with the predicted classes based on the max probability.  For the 1D case, {{X}} is the output of a {{softmax}} layer, and thus each row will contain a set of normalized class probabilities
