\description{
Plot the correlation (\code{Corr()}), the root mean square error 
(\code{RMS()}) between the forecast values and their observational 
counterpart, the slope of their trend (\code{Trend()}), the 
InterQuartile range, maximum-mininum, standard deviation or median absolute 
Deviation of the ensemble members (\code{Spread()}), or the ratio between 
the ensemble spread and the RMSE of the ensemble mean (\code{RatioSDRMS()}) 
along the forecast time for all the input experiments on the same figure 
with their confidence intervals.
}
\details{
Examples of input:\cr
Model and observed output from \code{Load()} then \code{Clim()} then 
\code{Ano()} then \code{Smoothing()}:\cr
(nmod, nmemb, nsdate, nltime) and (nobs, nmemb, nsdate, nltime)\cr
then averaged over the members\cr
\code{Mean1Dim(var_exp/var_obs, posdim = 2)}:\cr
(nmod, nsdate, nltime) and (nobs, nsdate, nltime)\cr
then passed through\cr
 \code{Corr(exp, obs, posloop = 1, poscor = 2)} or\cr
 \code{RMS(exp, obs, posloop = 1, posRMS = 2)}:\cr
 (nmod, nobs, 3, nltime)\cr
would plot the correlations or RMS between each exp & each obs as a function 
of the forecast time.
