Transtioned to all getter methods: getVal(), getNewVal(), updated(), using templates for all floats.
Finalized templates for getVal and getNewVal, including making <int> default so it does not have to be set for most getVal() and getNewVal() calls. Works for booleans as well. TO DO: Re-work and check ALL prior examples to ensure they use getVal, etc., and DON'T access value, newValue, isUpdated, directly.
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.
