Errors from the fann library are usually reported on stderr.
It is however possible to redirect these error messages to a file,
or completely ignore them by the <fann_set_error_log> function.
It is also possible to inspect the last error message by using the
<fann_get_errno> and <fann_get_errstr> functions.

/* Function: fann_set_error_log
Change where errors are logged to. Both <struct fann> and <struct fann_data> can be
casted to <struct fann_error>, so this function can be used to set either of these.
If log_file is NULL, no errors will be printed.
If errdata is NULL, the default log will be set. The default log is the log used when creating
<struct fann> and <struct fann_data>. This default log will also be the default for all new structs
that are created.
The default behavior is to log them to stderr.
