zone manager documentation

Since zone manager is in its early development stages and hopefully will greatly improve thanks to your feedback, it feels to be to early to write a full fledged documentation for zone manager. So far, the only "documentation" available are the commentaries in the source code of the examples included in the download. In order to make them more easy to find, the more important ones always start with MAD (most amazing discovery). Start with the "prefuse holiday camps" to get basic commentaries about the usage of zone manager, pass on to the "empty space for all" demos to see how zones can become flexible, and if you can still stand the source code, nothing particular new in "traffic lights" (except of adjusting the red and green zone depending on the size of the yellow zone).
