Sabl Decomposition - Data and Components Plot
.CS
sablplot(y, title="")
.AG y
object containing components `trend', `seasonal' and `irregular', 
typically the result of a call to the function `sabl'.  `y' may
optionally contain the component `calendar'. 
The decomposed series may be in a component named `transformed'
or `y'.
If it is not present, it is computed as the sum of
the `trend', `seasonal', `irregular', and `calendar' (if present) components.
.AG title
main title for the page of plots.
.SH EFFECT
This function produces one page of plots, showing in separate plots
the decomposed series, and
the trend, seasonal, calendar (if there is one),
and irregular components.
To the right of each plot is a bar
which portrays the relative scaling of that plot.
