* Added basic timer object, internal state machine, and unit tests * Added BACnetTimerStateChangeValue encode, decode, parse, print, and diff with unit tests * Changed handler of add/remove list element to check if the property is a BACnetLIST * Added BACnetLIST utility for handling WriteProperty to a list. * Fixed outlier ReadProperty object handlers to return zero when the RP parameter is NULL.
