        - vacancy_creation - search for neighbors of the same type and make a vacancy as a start position
        - interstitial_insertion - search for two neighboring voids; use them as start and final positions
                                    by inserting atom *atom_to_insert*
        - None - just use st and st2 as initial and final

    ###INPUT:
        - starting_calc (Calculation) - Calculation object with structure
        - st (Structure) - structure, can be used instead of Calculation
            - it_new (str) - name for calculation
        - st_end (Structure) - final structure

        - i_atom_to_move (int) - number of atom for moving starting from 0;
        - *mag_config* (int ) - choose magnetic configuration - allows to obtain different localizations of electron
        - *replicate* (tuple 3*int) - replicate cell along rprimd
        - i_void_start,  i_void_final (int) - position numbers of voids (or atoms) from the suggested lists
        - atom_to_insert  (str) - element name of atom to insert
        - atom_to_move (str) - element name of atom to move
        - it_new_folder or it_folder  (str) - section folder
        - inherit_option (str) - passed only to add_loop
        - inherit_magmom (bool) - if True than magmom from starting_calc is used, else from set

        - end_pos_types_z (list of int) - list of Z - type of atoms, which could be considered as final positions in vacancy creation mode

        - calc_method (list)
            - 'neb'
            - 'only_neb' - run only footer

        - x_start, x_final (array) - explicit xcart coordinates of moving atom for starting and final positions, combined with atom_to_insert
        - xr_start, xr_final (array) - explicit xred
        - rep_moving_atom (str)- replace moving atom by needed atom - can be useful than completly different atom is needed. 

        - upload_vts (bool) - if True upload Vasp.pm and nebmake.pl to server
        - run (bool)  - run on server

        - old_behaviour (str) - choose naming behavior before some date in the past for compatibility with your projects
            '020917'
            '261018' - after this moment new namig convention applied if end_pos_types_z is used

        - add_loop_dic - standart parameters of add()
