Saves the entire network to a configuration file.
The configuration file contains all information about the neural network and enables fann_create_from_file to create an exact copy of the neural network and all of the parameters associated with the neural network.
These three parameters (fann_set_callback, fann_set_error_log, fann_set_user_data) are NOT saved to the file because they cannot safely be ported to a different location. Also temporary parameters generated during training like fann_get_MSE is not saved.

Returns true on success, or false otherwise.
