* This is a very useful control, and 3rd-party apps should be able to
use it.
* But, there are planned improvements (making a better model/view
interface) which prevents making it part of the stable API yet.
* We install the headers for many things that are currently in libshared
(BColumnListView, BCalendarView, etc). So it makes sense to also provide
the lib in an "use at your own risk" way. Only the static library is
included, so apps linking against it should continue running on newer
Haiku versions even if the content of the lib changes.
* 3rd party application developers can now make use of those
experimental features without having to copypaste and fork the sources.
Some gristing mixup caused the non-secondary version of the lib to be
added to the non-secondary directory, which is what the main
architecture HaikuDevel is already doing.
