an Object Oriented Neural Engine

I found out. Forgot to setRows for hidden and output layer

my whole working test case:

@Test
public void testNeuralNetDelay() {
double[] data = { 1.0 };
DelayLayer iLayer = new DelayLayer();
iLayer.setLayerName("IN-DELAYED");
Layer hLayer = new TanhLayer();
hLayer.setLayerName("HID-TANH");
Layer oLayer = new TanhLayer();
oLayer.setLayerName("OUT-TANH");
NeuralNet nn = new NeuralNet();

iLayer = new DelayLayer();
iLayer.setRows(1);
iLayer.setTaps(4);

hLayer.setRows(4);
oLayer.setRows(1);

FullSynapse synapse1 = new FullSynapse();
FullSynapse synapse2 = new FullSynapse();

iLayer.addOutputSynapse(synapse1);
hLayer.addInputSynapse(synapse1);
hLayer.addOutputSynapse(synapse2);
oLayer.addInputSynapse(synapse2);

nn.addLayer(iLayer, NeuralNet.INPUT_LAYER);
nn.addLayer(hLayer, NeuralNet.HIDDEN_LAYER);
nn.addLayer(oLayer, NeuralNet.OUTPUT_LAYER);

double[] yyy = JooneTools.interrogate(nn, data);
assert yyy.length == 1;

}

btw. IMO it would be nice if joone indicate that layer doesn't have any rows instead of bare NullPointer
