/* Function: fann_save
Save 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.
Return:
The function returns 0 on success and -1 on failure.

FANN_EXTERNAL int FANN_API fann_save(struct fann *ann, const char *configuration_file);
/* Function: fann_save_to_fixed
Saves the entire network to a configuration file.
But it is saved in fixed point format no matter which
format it is currently in.
This is usefull for training a network in floating points,
and then later executing it in fixed point.
The function returns the bit position of the fix point, which
can be used to find out how accurate the fixed point network will be.
A high value indicates high precision, and a low value indicates low
precision.
A negative value indicates very low precision, and a very
strong possibility for overflow.
(the actual fix point will be set to 0, since a negative
fix point does not make sence).
Generally, a fix point lower than 6 is bad, and should be avoided.
The best way to avoid this, is to have less connections to each neuron,
or just less neurons in each layer.
The fixed point use of this network is only intended for use on machines that
have no floating point processor, like an iPAQ. On normal computers the floating
point version is actually faster.
