   This program simulates a 3 or 4-layer Neural Network, and can be used to
   simulate an arbitrary, complex, or non-linear function that would be
   difficult to implement by traditional methods. The Back Propagation
   method is used "teach" the network the desired function.
   Adjacent layers of the net are fully interconnected  that is, every
   neuron in layer 1 is connected to every neuron in layer 2, and every
   neuron in layer 2 is connected to every neuron in layer 3 (1->2, 2->3).
   With a 4-layer net, there is further interconnection: 1->2, 1->3, 2->3,
   2->4, 3->4.
