If G is a spectrum object G.Integral returns a list of length G.N stating the integral of the spectrum $-\frac{1}{\pi}\int_{-\infty}^{\infty}G(\omega)\mathrm{d}\omega$. Note that this value is independent of G.Emin and G.Emax and includes spectral weight outside the region stored in the spectral object. The integral is calculated during the creation of the spectral object and carried on during manipulation.
Print the integral of the spectra calculated in the definitions file for spectra.
