// Class: DebugStreamFull
//
// Purpose:
// An implementation of ostream designed for error and message logging.
// A DebugStream has a "level" assigned to it as a priority (lower number
// is higher priority). Multiple DebugStreams can be created. When
// output is written to one DebugStream, it is simultaneously written to
// all DebugStreams with a higher level.
//
// In this specific implementation, five debug levels are used. Only
// the highest priority messages go to debug1, but every message will go
// to debug5.
//
// Programmer: Jeremy Meredith
// Creation: November 16, 2000
//
// Modified:
// Jeremy Meredith, Fri Jun 1 17:18:03 PDT 2001
// Added the ability to check if a DebugStream was enabled.
//
// Brad Whitlock, Thu Mar 14 13:37:34 PST 2002
// Added exports.
//
// Jeremy Meredith, Thu Jan 16 11:40:29 PST 2003
// Made debug streams macros so that we could skip the logic to
// do the formatting if the debug output was disabled. Removed the
// ability to delete a debug stream automatically on close.
//
// Eric Brugger, Tue Aug 3 11:00:56 PDT 2004
// Change the DebugStreamBuf member to be a pointered value instead of
// a referenced value so that it works with the MIPSpro compiler.
//
// Jeremy Meredith, Tue May 17 11:20:51 PDT 2005
// Allow disabling of signal handlers.
//
// Mark C. Miller, Wed Apr 22 13:32:22 PDT 2009
// Changed name to DebugStreamFull
