mouse click: add red data point
shift + mouse click: add green data point
'r': re-initialize weights to random
's': shock the weights (change randomly a bit)
'q': change architecture (number of neurons, layers of neurons)
The network above is by default a 2-10-10-1 Neural Network.
It has 2 inputs (x and y coordinates), 2 layers of 10 hidden neurons each, and one output neuron that activates for green class.
