void fann_init_weights(resource ann, mixed training_data);
This function behaves similarly to fann_randomize_weights.
It will use the algorithm developed by Derrick Nguyen and Bernard Widrow [Nguyen and Widrow, 1990]
to set the weights in such a way as to speed up training.
The algorithm requires access to the range of the input data (ie, largest and smallest input), and therefore accepts a second argument, data, which is the training data that will be used to train the network.
