This for now shows the nodes that are registered in a manager, in the
hirarchy that is used. Redirects are displayed red, logicals gray and
normals in a e-style blue. If something is part of the focus history its
green.
During compilation of the objects introspection extension, the
clouseau_debug library is needed.
In Ubuntu machines, it seems that this MUST be specified in the
CMakeLists.txt. Without it, dlopen the extension fails on trying to find
a function present in the Clouseau library.
Thanks to Woohyun for using Ubuntu :-)
@fix
The objects introspection, that has always been as a core part, is now
an extension, and can be not used.
The directories structure allows other extensions to be developed inside
the Clouseau tree, even if they can be developed outside.
Other extensions will be added and the extensions feature will be
adapted to fit all their requirements.
