creating code to allow for multiple characteristics to be updated within event() call. To Do: define anogther sensor that supports multiple characteristics. also need to check that "new SpanEvent" works as expected from within a defined service.
putCharacteristics and checkNotifications now both call the same eventNotify routing. This is being done to prepare for services that will stream notifications back to client (like a temperature sensor, or pushbutton). TO DO: rename checkNotifications to check TimedResets, and rename SpanPut to something more generic.
Allow for any characteristic that is not read-only, which should leave out all string characteristics.
Upon reset, zero out all 8 bytes of UVal memory, instead of simply setting UVal.BOOL to false. This allows use of TimedReset for any characteristic with a numerical value.
Updated SpanRange to register itself automatically to the most recent Characteristic. This is more consistent with the overall framework and no longer requires user to access the range variable directly.
