Saves the entire network to a configuration file.
</p>
<p class="para">
The configuration file contains all information about the neural network and enables
<span class="function"><a href="function.fann-create-from-file.html" class="function">fann_create_from_file()</a></span> to create an exact copy of the neural network
and all of the parameters associated with the neural network.

<p class="para">
These three parameters ( <span class="function"><a href="function.fann-set-callback.html" class="function">fann_set_callback()</a></span>, <span class="function"><a href="function.fann-set-error-log.html" class="function">fann_set_error_log()</a></span>,
<span class="function"><strong>fann_set_user_data()</strong></span>) are NOT saved to the file because they cannot safely be ported
to a different location. Also temporary parameters generated during training like <span class="function"><a href="function.fann-get-mse.html" class="function">fann_get_MSE()</a></span>
is not saved.
