//
// Class Description:
//
// Class managing the per-thread state of the geometry, spanning those
// which have a per-thread state and their dependents.
// In particular it:
//       - owns the arrays that implement 'split' classes 
//       - owns 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.
