// Description:
//      Manage the per-thread state of solids - those which 
//        have a per-thread state and dependent classes (if any)
//   In particular it 
//       - owns the arrays that implement 'split' classes 
//       - classes/objects which are owned by the split classes.
//   Background: the classes/objects affected are  
//       - 'split' classes part of its state is per-thread,
//       - per-thread objects, in particular those which are owned 
//         by the split classes.
// Goal: Take ownership and control of per-thread state of 
//        classes to work with multi-threading. 
//       Offshoot of G4GeometryWorkspace, to deal with Solids.
// 
// Designed / created by John Apostolakis
// Interface design - review with Andrea Dotti.
// 
// First version: 4th Oct 2013
//    Created due to dependency issue with G4GeometryWorkspace 
// Working version:
