-! program that prints in a human readable format the convergence of the CIPSI algorithm.
-!
-! for all istate, this program produces

-! * a file "EZFIO.istate.conv" containing the variational and var+PT2 energies as a function of N_det
-!
-! * for istate > 1, a file EZFIO.istate.delta_e.conv containing the energy difference (both var and var+PT2) with the ground state as a function of N_det
