    00021   Diagram is generated using templates, which are stored in SD file templates.sdf
    00022   The SD file is usual SD file, which contain chemical structures and might contain data.
    00023   Only chemical structures are used. Subgraph isomorphisme search is executed and coordinates
    00024   of atoms are determined from templates. See Molecules, 11, 129-141 (2006) for algorithm decription.
    00025   Structures in SD file are converted in next manner:
    00026   1. All atoms, except explicit hydrogens, are replaced with generic ANY_ATOM (matched with any atom in subgraph isomorphisme search)
    00027   2. All bonds are replaces with generic ANY_BOND, which can be matched with any bond in molecule
    00028   3. All hydrogen are removed, but they are used for search-query and structure atom matching is believed fo be
    00029      sucessfukk if chemical structure contains more or equal number of hydrogens, than query. Using explicitly-defined hydrogens
    00030          on query enables ones to remove substitutors attachment for atom, which are sterically hidden on templates
    00031   if the file will not be found, predefined templates will be used
