 lyngby_nn_cddewda    - Classifier neural network, output, diag 2nd

       function ddEW = lyngby_nn_cddewda(Y, T, H, W)
       
       Input:  Y      Neural network output
               T      Target output
               H      Hidden layer output
               W      Output weights

       Output: ddEW   Derivative, a vector

       Diagonal approximation to the second order derivative of the
       error function for the classifier neural network with respect
       to the output weights.
