The data used to train the Neural Network:

Inputs:
    Using the head of the snake as the main reference point to calculate if there were obstacles 
    in front of the snake or sides.
        If one was there there was an obstacle in front.
        If zero there was no obstacle.
        
    The orientation of the snake head to the apple like a compass.
        Calculated the angle between the snake and head
