    Prepare needed files for NEB
    Provides several regimes controlled by *search_type* flag:
        - existing_voids - search for voids around atom and use them as a final position 
        - 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*
            

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


        - i_atom_to_move (int) - number of atom for moving;
        - *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) - number of voids from the suggested lists
        - atom_to_insert  (str) - element name of atom to insert
        - it_new_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

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

        - x_start, x_final (array) - explicit coordinates of moving atom for starting and final positions, combined with atom_to_insert
        
        - upload_vts (bool) - if True upload Vasp.pm and nebmake.pl to server

    Prepare needed files for NEB
    Provides several regimes controlled by *search_type* flag:
        - existing_voids - search for voids around atom and use them as a final position 
        - 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  (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

    ###RETURN:
        None

    ###DEPENDS:

    ###TODO
    1. Take care of manually provided i_atom_to_move in case of replicate flag using init_numbers 
    2. For search_type == None x_m and x_del should be determined for magnetic searching and for saving their coordinates
    to struct_des; now their just (0,0,0)

    addtype - type of adding: ['central',]; 'central' means that impurity 
    will be placed as close to the geometrical center of cell as possible.

    will be added

    even if 'it_to' is empty it will try to find files in 'geo_folder + struct_des[it_new].sfolder+'/from' ' folder.
    'ise_to' also can be empty

    if 'copy_geo_from' is not empty, then programm copy all files from folder 'copy_geo_from' to 
    folder 'geo_folder + struct_des[it_to].sfolder+"/"+it_to' or  'geo_folder + struct_des[it_new].sfolder+"/from" '  

    'find_close_to' is tuple of three reduced coordinates of point close to which you want to find impurity. If empty - ignored; 

    'add_to_version' is integer number added to each 'verlist_to' number to produce ver_new.
    
    'only_version' - if == [v,], then instertion will be provided only for v. If None insertion will be made in all found versions

    If you want to add impurity to relaxed structure ...

    'fine' - integer number; allows to reduce number of small steps for defining center


    Possible addtype's:
    'central' - add one atom to the pore which is most close to  the center of the cell but with reduced coordinates less than 0.5 0.5 0.5
    'all_pore'  - add atoms in every found pore
    'all_local' - add atoms to every local point which allows to visualise topology of pores.
    'gb' - uses self.gbpos and places atom close to this value assuming that it will be at gb
    'grain_vol' - uses self.gbpos and assuming that cell contains two gb and two equal grains, places atom close to the centre of grain; y and z can be arbiratry


    put_exactly_to - will add impurity to this point 
    find_close_to - will try to find closest void and insert pore here.

    check_pore_vol - allows to estimate volume of pores; has problems for big cells

    Add impurities in pores.

    Input:
    it_new - name of new structure with impurity
    
    impurity_type - name of impurity from Mendeley table, for example 'C'
    
    addtype - type of adding: ['central',]; 'central' means that impurity 
    will be placed as close to the geometrical center of cell as possible.
    
    it_to , ise_to , verlist_to - completed calculations in which impurity 
    will be added
    
    if 'verlist_to' is empty, function will try to find geometry files in 'geo_folder + struct_des[it_to].sfolder' folder;
    even if 'it_to' is empty it will try to find files in 'geo_folder + struct_des[it_new].sfolder+'/from' ' folder.
    'ise_to' also can be empty

    if 'copy_geo_from' is not empty, then programm copy all files from folder 'copy_geo_from' to 
    folder 'geo_folder + struct_des[it_to].sfolder+"/"+it_to' or  'geo_folder + struct_des[it_new].sfolder+"/from" '  

    'find_close_to' is tuple of three reduced coordinates of point close to which you want to find impurity. If empty - ignored; 

    'add_to_version' is integer number added to each 'verlist_to' number to produce ver_new.
    
    'only_version' - if == [v,], then instertion will be provided only for v. If None insertion will be made in all found versions

    If you want to add impurity to relaxed structure ...

    'fine' - integer number; allows to reduce number of small steps for defining center


    Possible addtype's:
    'central' - add one atom to the pore which is most close to  the center of the cell but with reduced coordinates less than 0.5 0.5 0.5
    'all_pore'  - add atoms in every found pore
    'all_local' - add atoms to every local point which allows to visualise topology of pores.
    'gb' - uses self.gbpos and places atom close to this value assuming that it will be at gb
    'grain_vol' - uses self.gbpos and assuming that cell contains two gb and two equal grains, places atom close to the centre of grain; y and z can be arbiratry


    put_exactly_to - will add impurity to this point 
    find_close_to - will try to find closest void and insert pore here.

    check_pore_vol - allows to estimate volume of pores; has problems for big cells

    replace_atom - if not None, than the specified atom is substituted

    'coseg' assumes pure cell and creates only coseg cases.
    cosegregation cases of course should be the same for two regimes, however co-segregation configuations after 'coseg' is more easy to relax.
    'grainvol' - searching for pairs in grain volume

    two regimes for bulk cells:
    'bulk_triple' - used for bulk cells without grain boundaries; first step is searching for pairs, second step for triples.
    'bulk_pairs' - used for bulk cells without grain boundaries; searching for pairs.



    new_name - name of created structures; at first should be added to struct_des[]
    in_calc - Calculation() type or path to geo file
    region - list of numbers which determine region
    central_atoms - list of atoms for which pairs are constructed (Warinig! numbers in new array xcart_pores!);
    - parameter to change mode;

    xcart1imp - coordinates of first interstitial in the  grain interior 

    input_dlist_coseg - list of configurations with cosegregation cases. Needed to construct corresponding segregation cases. the format is quiet tricky

    prec - precision of lengths used to determine unique positions.

    gvolume_config_num - number of configuration with two atoms in grain volume choosen by user (usually should be the most favourable) 

    gbpos - position of grain boundary

    take_final_rprimd_from - path to geo file from which rprimd will be used


    target_znucl - numbers of target atoms

    max_dist_between_atoms - now at least used for 'bulk_pairs' and 'bulk_triple'; maximum length of found pairs.

    three regimes for cells with grain boundaries:
    'segreg' assumes that in_calc contains carbon atom in grain volume, and creates all cases; 
    'coseg' assumes pure cell and creates only coseg cases.
    cosegregation cases of course should be the same for two regimes, however co-segregation configuations after 'coseg' is more easy to relax.
    'grainvol' - searching for pairs in grain volume

    two regimes for bulk cells:
    'bulk_triple' - used for bulk cells without grain boundaries; first step is searching for pairs, second step for triples.
    'bulk_pairs' - used for bulk cells without grain boundaries; searching for pairs.



    new_name - name of created structures; at first should be added to struct_des[]
    in_calc - Calculation() type or path to geo file
    region - list of numbers which determine region
    central_atoms - list of atoms for which pairs are constructed (Warinig! numbers in new array xcart_pores!);
    - parameter to change mode;

    xcart1imp - coordinates of first interstitial in the  grain interior 

    input_dlist_coseg - list of configurations with cosegregation cases. Needed to construct corresponding segregation cases. the format is quiet tricky

    prec - precision of lengths used to determine unique positions.

    gvolume_config_num - number of configuration with two atoms in grain volume choosen by user (usually should be the most favourable) 

    gbpos - position of grain boundary

    take_final_rprimd_from - path to geo file from which rprimd will be used


    target_znucl - numbers of target atoms

    max_dist_between_atoms - now at least used for 'bulk_pairs' and 'bulk_triple'; maximum length of found pairs.
