_D_e_s_c_r_i_p_t_i_o_n:

     This function loops over the elements of a StringSet and 
     evaluates the specified function on each value. Since the
     'StringSet-class' is an  opaque, internal data structure of the
     libstree library, this method takes care of handling  the details
     of the iteration.

     _X = "_S_t_r_i_n_g_S_e_t", _F_U_N = "_f_u_n_c_t_i_o_n" the first argument is the
          'StringSet-class' whose elements are to be processed
          sequentially. The second argument is a function which is
          called for each element. The argument to this function is the
          string from that element of the string set.
