Supersonic block has landed (Power Trio tutorial/example app)

[Bertrand Delacretaz]

I've just committed the new "supersonic" block, a tutorial/example app 
called "Supersonic Tour of Apache Cocoon", focused on Pipelines, Flow, 
Forms (aka "the Power Trio").

It is accessible from the "blocks with samples" page if you run the 
current Cocoon CVS version.

The tutorial is meant to be studied independently of other docs, and 
give a quick overview of the most important components of Cocoon.

There are probably a few typos here and there, and I'm no Forms guru 
(yet..) so enhancements are certainly possible (for example: why does 
this "Calendar" link show up next to the date entry fields ;-)

Enjoy, and as always feedback and contributions are very welcome!
