A neural network is a string, containing ASP-formatted data as atoms as:
- neuron(I,T): neuron of id I is of type T (T in IXANO)
- output(I): neuron of id I is an output neuron
- edge(I,J): there is an edge between neurons of id I and J
The object assume that inputs and outputs attributes are iterables
of pairs (f, n), where f is a function and n the number of neuron
associated to the function.
For input neurons, function takes no parameters, and should return
