 Program that extracts the :option:`determinants n_states` lowest states of the Hamiltonian within the set of Slater determinants stored in the EZFIO folder. 
  
 If :option:`determinants s2_eig` = True, it will retain only states 
  
 which corresponds to the desired value of :option:`determinants expected_s2`.
