//
// $Log: cmnLogger.cpp,v $
// Revision 1.6  2007/04/26 19:33:56  anton
// All files in libraries: Applied new license text, separate copyright and
// updated dates, added standard header where missing.
//
// Revision 1.5  2006/11/20 20:33:19  anton
// Licensing: Applied new license to cisstCommon, cisstVector, cisstNumerical,
// cisstInteractive, cisstImage and cisstOSAbstraction.
//
// Revision 1.4  2005/09/26 15:41:46  anton
// cisst: Added modelines for emacs and vi.
//
// Revision 1.3  2005/05/19 19:29:01  anton
// cisst libs: Added the license to cisstCommon and cisstVector
//
// Revision 1.2  2005/02/11 19:50:44  anton
// cmnLogger: Added two methods to halt/resume the log to the default file.
//
// Revision 1.1  2004/09/01 21:12:02  anton
// cisstCommon: Major update of the class register and the logging system.
// The class register is now a singleton (as in "Design Patterns") and doesn't
// store any information related to the logging (i.e. global lod, multiplexer
// for the output).  The data related to the log is now regrouped in the
// singleton cmnLogger.  This code is still fairly experimental (but tested)
// and the documentation is missing.  These changes should solve the tickets
// #30, #38 and #46.
