Turnout class split into a base class for common code and specific subclasses for Servo, DCC, VPIN and LCN turnouts. Interface further narrowed to reduce direct access to member variables. Turnout creation command handling has been moved into the DCCEXParser class. Turnout function and parameter names changed to make the Throw and Close functionality explicit. Turnout commands <T id C> (close) and <T id T> (throw) added.
