Message:

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.
