//
// ELseverityLevel.cc - implement objects that encode a message's urgency
//
//      Both frameworker and user will often pass one of the
//      instantiated severity levels to logger methods.
//
//      The only other methods of ELseverityLevel a frameworker
//      might use is to check the relative level of two severities
//      using operator<() or the like.
//
// 29-Jun-1998 mf       Created file.
// 26-Aug-1998 WEB      Made ELseverityLevel object less weighty.
// 16-Jun-1999 mf       Added constructor from string, plus two lists
//                      of names to match.  Also added default constructor,
//                      more streamlined than default lev on original.
// 23-Jun-1999 mf       Modifications to properly handle pre-main order
//                      of initialization issues:
//                              Instantiation ofthe 14 const ELseverity &'s
//                              Instantiation of objectsInitialized as false
//                              Constructor of ELinitializeGlobalSeverityObjects
//                              Removed guarantor function in favor of the
//                              constructor.
// 30-Jun-1999 mf       Modifications to eliminate propblems with order of
//                      globals initializations:
//                              Constructor from lev calls translate()
//                              Constructor from string uses translate()
//                              translate() method
//                              List of strings for names in side getname() etc.
//                              Immediate initilization of ELsevLevGlobals
//                              Mods involving ELinitializeGlobalSeverityObjects
// 12-Jun-2000 web      Final fix to global static initialization problem
// 27-Jun-2000 web      Fix order-of-static-destruction problem
// 24-Aug-2000 web      Fix defective C++ switch generation
// 13-Jun-2007 mf       Change (requested by CMS) the name Severe to System
//          (since that his how MessageLogger uses that level)
// 21-Apr-2009 mf   Change the symbol for ELsev_success (which is used
//                      by CMS for LogDebug) from -! to -d.
