Functions
void	pbl_freq_track_init (struct pbl_freq_track *ft, const struct pbl_freq_track_params *params)
	Initialize a tracker with no estimate.
void	pbl_freq_track_seed (struct pbl_freq_track *ft, double hz, double gate_s, uint64_t t_ms)
	Start from a known frequency, e.g.
int	pbl_freq_track_update (struct pbl_freq_track *ft, double hz, double gate_s, uint64_t t_ms)
	Feed a measurement.
double	pbl_freq_track_get (const struct pbl_freq_track *ft)
	Get the estimate.
double	pbl_freq_track_get_dev (const struct pbl_freq_track *ft)
	Get the standard deviation of the estimate.
