CRgChange Class
class CRgChange: public CRgChange
This class is used by CRgProcessor, CRgSubState and CRgState to maintain information about whether their states were changed since the last compilation ( CRgProcessor::Compile). If you are setting up the scanner statically in the CRgProcessor::Initialize method as in the deals sample then you do not have to worry about checking the flag since you basically need to call Compile only once after you have set everything up.
