//	The building block for a predictor is CPredictor. It offers three abstract methods that 
//	should be overriden by derived classes:
//
//	virtual void Update(int NextElement);	
//	Call this method to update the predictor with the next element of the sequence. 
//	
//	virtual bool Prediction(int &Prediction);
//	Call this method to get a reasonable successor for the sequence. If the return value is
//	false, the prediction is bad and should not be used.
//
//	virtual void Reset();
//	Call this method to reset the predictor (i.e. lose its memory)
