I'm not sure wether the first parameter should be a String or a Logger
(which of course must belong to the managed hierarchy). In other words,
should the manager act on loggers/categories that already exist, or
should it create them on the fly when requested ?
And also, couldn't Hierarchy and HierarchyManager be merged ? If there's
no restriction for getting a manager once we know the hierarchy, it
would be better IMO to let the Hierarchy manage itself its category
tree, or we will end up with Hierarchy having only getLoggerFor() and
all other methods moved to HierarchyManager.
Thoughts ?

Oh, forgot to say : if can be useful to anyone, I can post it.
And also, please find attached a StreamTargetFactory which allows to
configure StreamTargets with LogKitManager using OutputStreams stored in
the context (System.out/System.err are predefined entries).
