// Version:      2.0
// Date:         5/02/04
// Author:       Fan Lei 
// Organisation: QinetiQ ltd.
// Customer:     ESA/ESTEC
//
//
// CHANGE HISTORY
// --------------
//
// Version 2.0, 05/02/2004, Fan Lei, Created.
//    After changes to version 1.1 as in Geant4 v6.0
//     - Mutilple particle source definition
//     - Re-structured commands
//     - old commands have been retained for backward compatibility, will be
//       removed in the future. 
//
//
// 20/03/2014, Andrew Green - Modifications for MT
//      - Added a check to force only one thread to parse the macro file
//          This information is fed into the GPS which now has a split mechanism for the large data (hence need to only read in 1 thread)
//      - Thread ID used is 0, so *should* work under interactive mode as well - may need checking, or the may be another way...
