// Class description:
//
//   Manages 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.
