virtual bool checkRTTI (const char *typenameStr)=0
 This function is only implemented by concrete classes and triggers the actual RTTI check through matchRTTI();.
 
bool matchRTTI (const char *typenameStr)
 Performs a check to see if the given typename string matches this class' This needs to be implemented in -all- subclasses, even abstract ones.
