fann_get_activation_function — Returns the activation function
Get the activation function for neuron number neuron in layer number
layer, counting the input layer as layer 0.
It is not possible to get activation functions for the neurons in the input layer.
The return value is one of the activation functions constants.
annNeural network resource.

neuronNeuron number.
Learning functions constant or -1
if the neuron is not defined in the neural network, or false on error.
