v_offset and σ_sqrt2 should be fields of m

Lines 59 to 61 in a639217

	function cdf(m::GaussianMixtureCCFMask, v_lo::Real,v_hi::Real, i::Integer)
	m.cdf_normalization[i]*( erf((v_hi-v_offset[i])/σ_sqrt2[i]) - erf((-v_lo-v_offset[i])/σ_sqrt2[i]) )
	end

Could also add an assert to make sure index is valid for the number of mixtures, i.e. 1 <= i <= length(m.weight)
