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

     Produces a 6 panel plot.  The first panel contains the Mahalanobis
     distances for the units in the subset of size 'subset.size'.  The
     backgrounds of the 5 remaining plots are quantiles of these
     distances.  The dark lines in the 5 remaining plots are the
     trajectories of the units entering the subset during each of the
     next 5 steps of the forward search.

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

     fwdmvQuantilePlot(x, subset.size, probs = "default", page = 1)

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

       x: an 'fwdmv' object.

subset.size: an integer specifying (by its size) the subset to be used
          in the first panel.

   probs: an ordered numeric vector of probabilities used by the
          quantile function.

    page: an integer specifying the page.  When 'page == 1' the
          trajectories for the next 5 steps are drawn, when 'page == 2'
          the next 5 steps are skipped and trajectories for the 5
          following step are drawn, etc.

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

     when 'probs == "default"' the following quantiles are computed:
     0.025, 0.05, 0.125, 0.25, 0.50, 0.75, 0.875, 0.95, 0.975.

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

     an empty list is invisibly returned.

_S_e_e _A_l_s_o:
