Added getActivations method to NeuralNetwork class that returns each neuron in the form of a 2D array of doubles. Neuron values are stored as SimpleMatrix objects in an ArrayList inside the guess() method and returned in a separate method that converts the ArrayList of SimpleMatrix objects to the 2D array.
