Feature (contd.): Variable Fields - removed protocol subclass implementations of isProtocolFrameValueVariable() since the updated implementation in the base abstract class is now sufficient. Updated subclass implementations of protocolFrameValueVariableCount() to query the base class and use the return value in its calculation
