New Features Add pole-base Padé analytic continuation ~gftool.polepade (41d57537). Allows determining number of poles avoiding overfitting. Least-squares based approach allowing to include uncertainties of input data. Add ~gftool.linearprediction module (b1c8f636). Linear prediction can be used to extend retarded-time Green's functions. Add Padé-Fourier approach to Laplace transform (fe1ac173). Padé-Fourier allows to significantly reduce the truncation error. This allows for contours closer to real-axis for a given maximal time. Linear Padé approximant ~gftool.fourier.tt2z_pade based on simple poles. Quadratic Hermite-Padé approximant ~gftool.fourier.tt2z_herm2 including quadratic branch cuts but introducing ambiguity which branch to choose. Module ~gftool.hermpade implements the necessary approximants. Add lattice ~gftool.lattice.box with box-shaped DOS (09974a09). Internal improvements Use numpy.testing.assert_allclose for tests, providing more verbose output (dbb8fd7c). Documentation Start to adhere more closely to numpydoc (40d57d45).
