// ****************************************************************************
// Class: TimingsManager
//
// Purpose:
// Allows other modules in VisIt to not worry about timings.
//
// Programmer: Hank Childs
// Creation: March 10, 2001
//
// Modifications:
// Eric Brugger, Mon Nov 5 14:14:12 PST 2001
// I added the methods Enable and Disable.
//
// Brad Whitlock, Thu Mar 14 13:37:34 PST 2002
// Added exports.
//
// Brad Whitlock, Fri Sep 20 16:14:30 PST 2002
// I made StopTimer return the time.
//
// Jeremy Meredith, Fri Oct 4 16:48:26 PDT 2002
// Added number of current timings and indented output based on that value.
//
// Brad Whitlock, Mon May 19 12:36:50 PDT 2003
// Added MacOS X code.
//
// Mark C. Miller, Wed Apr 21 12:42:13 PDT 2004
// I added static methods, TimeSinceLastArrival, DiffTime
// I defined the TIMEINFO macro and restructured code to use it
//
// Mark C. Miller, Wed Nov 2 09:07:05 PST 2005
// Added optional force argument to Start/Stop methods to permit
// getting timer info in return value even if not logging to file
//
// Mark C. Miller, Fri Nov 11 09:45:42 PST 2005
// Added TimeSinceInit method, changed name of TimeSinceLastCall to
// TimeSinceLine
//
// Mark C. Miller, Wed Aug 2 19:58:44 PDT 2006
// Added Finalize method
//
// Mark C. Miller, Thu Aug 3 13:33:20 PDT 2006
// Added StopAllUnstoppedTimers, ClearValues and GetNValues()
//
// Mark C. Miller, Tue Aug 15 20:20:58 PDT 2006
// Eliminated numTimings. Fixed bug where DumpTimings would ClearValues
// but not also reset numTimings.
//
// Hank Childs, Fri Sep 14 12:58:59 PDT 2007
// Overhauled the handling of the "values" array, since it has been
// mis-used for over a year and been giving incorrect results.
//
// Dave Pugmire, Mon Feb 23 13:29:49 EST 2009
// Added LookupTimer.
//
// Hank Childs, Sat Apr 11 23:41:27 CDT 2009
// Add mode for NoOutputs.
//
// Hank Childs, Sat Feb 20 16:45:48 CST 2010
// Add method for getting the NeverOutput data member.
//
