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

     Core-generating function for 'strucplot' returning a function
     producing sieve plots.

_U_s_a_g_e:

     struc_sieve(sievetype = c("observed","expected"))

_A_r_g_u_m_e_n_t_s:

sievetype: logical indicating whether rectangles should be filled
          according to 'observed' or 'expected' frequencies.

_D_e_t_a_i_l_s:

     This function is usually called by 'strucplot' (typically when
     called by 'sieve') and returns a function used by 'strucplot' to
     produce sieve plots.

_V_a_l_u_e:

     A function with arguments: 

residuals: table of residuals.

observed: table of observed values.

expected: not used by 'struc_sieve'.

 spacing: object of class '"unit"' specifying the space between the
          tiles.

      gp: list of 'gpar' objects used for the drawing the tiles.

split_vertical: vector of logicals indicating, for each dimension of
          the table, the split direction.
