// Class description:
//
// Class managing the per-thread state of particles, those which
// have a per-thread state and dependent classes (if any).
// In particular, it owns the arrays that implement 'split' classes
// and classes/objects which are owned by the split classes.
// 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.
