int gol_sav ( const double * Data, int Len, int Formula, int Cyc, double * Sm, double * Smder )

gol_sav(Data, Len, Formula, Cyc, Sm, Smder): smooths the Len-long array Data Cyc times using the Golay-Savitzky formula. Formula is 5,7,9 or 11 (the number of G-S points): Formula<5 is rounded to 5, Formula>11 down to 11, the numbers 6, 8, 10 will be rounded up. If Sm!=NULL, then the smoothed points will be put into it. If Smder!=NULL, then the smoothed derivatives will be put into it. It is an error if both are NULL at the same time. Return value: the number of smoothing cycles performed.
