[xmlblaster] a new demo: GraphicChat

[Michele Laghi <laghi at swissinfo.org>]

Hallo everybody,
there is a new little demo to show how to simply implement graphical 
java clients to xmlBlaster.

It is based on JHotDraw (http://www.jhotdraw.org) which I found written 
with very clean code. It is very simple to integrate with xmlBlaster.

With just a few lines of code a "graphical chat" has been implemented, 
i.e. several clients can simultaneously draw on a graph and instantly 
get changes from the other clients.

Have a look at it and as always improvements are welcome. And who knows, 
more graphical examples can be done !!

Saluti
