    >>> el_by_sym = ElBySym(H='hydrogen')
    >>> el_by_sym['H']

    >>> el_by_sym.inverse['hydrogen']
    'H'
    >>> el_by_sym.keyname
    'sym'
    >>> el_by_sym.valname
    'el'
    >>> el_by_sym.el_for['H']
    'hydrogen'
    >>> el_by_sym.sym_for['hydrogen']
    'H'
    >>> el_by_sym.inverse.el_for['H']
    'hydrogen'
    >>> el_by_sym.inverse.sym_for['hydrogen']
