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

     A pairs like plot.  The subsets within each group are represented
     by concentric ellipses drawn to contours of the bivariate normal
     distribution.  Units in the tentative groups that are not in the
     subsets are plotted as points and the indices of the unassigned
     units are plotted as text.

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

     fwdmvEllipsePlot(x, subset.size, plot.diagonal = TRUE)

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

       x: an 'fwdmv' object.

subset.size: an integer specifying (by its size) which subset to use to
          draw the ellipses.

plot.diagonal: a logical value.  If 'TRUE' then univariate boxplots are
          drawn along the main diagonal.

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

     an empty list is invisibly returned.

_N_o_t_e:

     For initial 'fwdmv' objects the unassigned units are plotted as
     points.
