// Modifications:
//   Brad Whitlock, Thu Nov 13 11:55:17 PDT 2003
//   I made it throw a VisItException if the file can't be opened.

//   Brad Whitlock, Thu Dec 18 11:18:06 PDT 2003
//   I made it call CreateNode with the new completeSave flag set to false.

//   Brad Whitlock, Thu Feb 17 15:55:29 PST 2005
//   I removed the exception and made the function return a bool.
