Now to create the neural network.  The linear network
 must have tapped delay in order to learn the time-
 shifted correlation between P and T:  NEWLIN creates a
 linear layer.

 >> net = newlin([-3 3],1,[0 1],0.1);

 [-3 3] is the expected input range.  The second argument
 is the number of neurons in the layer.  [0 1] specifies 
 one input with no delay and one input with a delay of 
 one.  The last argument is the learning rate.
