// current call stack. This string will be stored in the BaseExc
// object; the string is accesible via the BaseExc::stackTrace()
// method.
//
// setStackTracer(0)
//
// removes the current stack tracing routine. When an exception
// derived from BaseExc is thrown, the stack trace string stored
// in the BaseExc object will be empty.
//
// stackTracer()
//
// returns a pointer to the current stack-tracing routine, or 0
// if there is no current stack stack-tracing routine.
