//
// ErrorObj 	is the representation of all information about an error
//		message.  The system uses this heavily:  ErrorLog forms an
//		ErrorObj to pass around to destinations.  A physicist is
//		permitted to use ErrorObj to form a message for potential
//		logging.
//
// 7/8/98  mf	Created file.
// 6/15/99 mf,jvr  Inserted operator<<(void (*f)(ErrorLog&)
// 7/16/99 jvr  Added setSeverity() and setID functions
// 6/6/00 web	Adapt to consolidated ELcout/X
// 6/14/00 web	Declare classes before granting friendship.
// 5/7/01  mf   operator<< (const char[]) to avoid many instantiations of
//              the template one for each length of potential error message
// 6/5/01  mf   Made set() and clear() public.  Added setReactedTo.
// 6/6/06  mf   verbatim.
