Added new pattern ObservedValue, contrary to Cacheable.
- essentially updates immediately and caches a value for off-line use, safe-
guard with mutexes.
- added unit test for ObservedValue.
- factored threeNumbers stub out of CacheableUnitTest, also used the stub in
ObservedValueUnitTest.
- we may now signOn() to Notification with a priority.
- Cacheable can also update now via notification channels not just for global
updates.
- Observable can now also instantiate the channels directly if given a list.
This was necessary as Cacheable or ObservedValue are instantiated in the
constructor, too, and if listening to channels, these must already be
present.
- FIX: Channels::addChannels() used NDEBUG wrong way round.
- ObservedValue::get() returns reference.
