/** 
    @brief Macros for output instead of direct cout<<
    Can be switched on or off globally,
    can be used for logging to file, too.    
    
    The significant difference to BIASDebug is that this macro does not
    touch the class hierarchy and does not add artificial class members.
    But: This debugging scheme supports only levels, not flags.
    If you really need more granular debugging/outputs look at BIAS/Base/Debug.hh .
