gf: security in the case beta<0 added in the mesh construction gf: inline added in slice test/triqs/gf: test of on_mesh() added gfs: scalar for two-real_times test/triqs/gf/ renamed in gfs, test gf_retw.cpp completed gfs: evaluator homogeneised two_times: evaluator corrected test/triqs/gf/ renamed in gfs, test gf_retw.cpp completed + Correction after rebase Fix a test : gf_re_im_freq_time There is an issue with the last point. To be fixed.
