  KS_CDF_CONF_PLOT - Plot gray patch of confidence around a CDF

     H = vlt.stats.ks_cdf_conf_plot(XVALUES, MINCDF, MAXCDF, XMIN,XMAX);

    Plots a gray 'patch' around a sample CDF indicating the confidence in
    the true distribution.  

    It is assumed the XVALUES, MINCDF, and MAXCDF are returned from
    vlt.stats.ks_cdf_conf.  Use XMIN and XMAX to specify the minimum and maximum X values
    used for the plot.
