Hey Joseph, I wonder why `Base.:+`, `Base.:-` and `Base.:*` are defined for subtypes of `AbstractStorage` but not for the Green's function types. Am I missing something? Looks like a mere...

Use exact expressions $G(\tau_1, \tau_2) = G(\tau_1 - \tau_2, 0)$, $G(\tau, 0) = \xi G(\tau + \beta, 0)$ in imaginary time interpolation for `ImaginaryTimeGF`, `FullTimeGF`, and `TimeInvariantFullTimeGF`.

Dear Joseph, I think there might be a problem with the interpolation for imaginary time Green's functions. The interpolation result seems not to be time-translational invariant. I was expecting that...
