smoothed data plot

I've written a little isis wrapper which will smooth the histogram
data before plotting (using gsmooth).  You can see an example of
Gaussian smoothed vs rebinned data on the ISIS examples contrib page:

http://space.mit.edu/CXC/ISIS/contrib/Smooth_vs_rebin/Smooth_vs_rebin.html

and get the functions, if you want them:

    splot_data_counts(hist_index, sigma[,color]);
    splot_data_flux((hist_index, sigma[,color]);

(which are analogous to isis plot_data_counts() and plot_data_flux() );

One advantage of wrapping the smoother into a plot function is that it
doesn't returned smoothed data, which will help prevent risky
quantitative analysis of it.  Another is that it makes it easier to
make a plot of smoothed data.

Exercise 1: Write a similar wrapper for hplot, called shplot.
