-/* As this interface is more or less a conversion from `OnlineRealtimeEngine`, what follows are
- * the methods that were public, but are no longer going to be public as far as the interface
- * is concerned. I've checked via searching the Magnopus org for uses of these, and initial findings
- * show these can be hidden, although some client validation wouldn't go amiss.
- * In reality, OnlineRealtimeEngine isn't going anywhere and will continue to exists behind the interface, so these
- * methods are not being deleted, they're just not being exposed to clients or CSP-core.
- * They'll still be called by methods internal to the module.
- *

- * OnlineRealtimeEngine::AddEntity (We think only Ichabod uses this, we think incorrectly. _Definitely_ need to check this one. Potential full
- * deletion candidate) OnlineRealtimeEngine::LocalDestroyEntity OnlineRealtimeEngine::LockEntityUpdate OnlineRealtimeEngine::UnlockEntityUpdate
- * OnlineRealtimeEngine::SetConnection
- * OnlineRealtimeEngine::RegisterEntityScriptAsModule (Potential full deletion candidate)
- * OnlineRealtimeEngine::BindNewEntityToScript (Potential full deletion candidate)
- * OnlineRealtimeEngine::RetrieveAllEntities
- * OnlineRealtimeEngine::LocalDestroyAllEntities
- * OnlineRealtimeEngine::SetSelectionStateOfEntity (Covered by SpaceEntity Select/Deselect)

- * OnlineRealtimeEngine::ResolveEntityHierarchy
- * OnlineRealtimeEngine::Initialise
- * OnlineRealtimeEngine::Shutdown
- * OnlineRealtimeEngine::GetPendingAdds
- * OnlineRealtimeEngine::CheckIfWeShouldRunScriptsLocally
- * OnlineRealtimeEngine::RunScriptRemotely (Public interface to this is EntityScript::RunScript)
