BSpline::BSpline<double> iterative_spline	(	const MArray< double, 1 > &	x,
		const MArray< double, 1 > &	y,
		MArray< bool, 1 > &	mask,
		const double	cutoff,
		const double	kappa
	)

Fit an approximating spline with cutoff wavelength (in units of x) of cutoff to a set of {x,y} data, then kappa-sigme clip around the spline at and reject at kappa times the stddev. Fit a spline again with the clipped values excluded. Return a spline after another round of iteration.
