Log Message:
Made better distinctions between Value and Condition behaviors, and added
ability to easily adapt from one to the other.  Added 'events.subscribe()'
to allow automatic re-subscription to a source, with automatic or manual
cancellation (automatic happens if the subscriber goes away).  Revised
derived values and all types of conditions to work via delegation rather
than inheritance, making use of 'events.subscribe()'.  We're now in a lot
better shape for adding logical operations on conditions and making
it easier to derive conditions or values from other conditions or values.
