Hi,
Some interfaces we support, such as domain might not be bound to a single
path, but rather anything under a path 'directory'. This patch allows the
SBUS to register a fallback path that would route any messages under a
given anchor to a handler of an interface.
Pavel Brezina had an idea of making the handler interface-driven instead
of path-driven and I would like to match the paths based on object that
were really found and exist, but I believe this patch is good enough to
allow further development on master and we can improve on it later on.
