st: update simpplot available from SSC

[Maarten Buis <maartenlbuis@gmail.com>]

Thanks to Kit Baum an update of the -simpplot- package is now
available from SSC. It can be installed by typing in Stata -ssc
install simpplot, replace- or -adoupdate, update- when a previous
version of -simpplot- has already been installed, or by typing -ssc
install simpplot- when -simpplot- has not yet been installed.

-simpplot- describes the p-values returned by a simulation experiment
by plotting for each possible nominal significance level the deviation
from that significance level. Additionally it also plots the region in
which one would expect most experiments to remain it the test that is
being simulated is well behaved and if you were repeating that
experiment many times. Examples of these simulations and graphs can be
seen here: <http://www.maartenbuis.nl/software/simpplot.html>.

This update fixes a couple of smaller bugs and adds the -by()- option.
The latter can be useful as often simulation experiments can consist
of many scenarios, and plotting them all in one graph would lead to
too much clutter.

Hope that some of you will find it useful,
Maarten
