please improve the documentation

some things that are missing in the documentation :
- a reference documentation (to complement the tutorial, which is great but not exhaustive)
- some "ready to deploy" samples (source code available on a http server) corresponding to the tutorial, so that you can deploy them on your portal using the "widget deployment" interface, and check that they behave as expected, before trying your own components. (this means that the expected behaviour is documented too !)

for some days, I have wondered why a component I developed did not behave as expected on my bubbletop page, whereas it worked in the preview. would hav not lost so much time if there was a documented "ready to deploy" component.
