//It might be better to organize the quarks in a k-d tree structure, for easier
//partitioning of the quarks based on spatial information.
//But for now, we just assume the quarks each script engine operates on form a rectangle shape.
//So we just use xmin,ymin and xmax,ymax to identify the rectange; and use a List structure to
//store the quarks.
//Quark size is defined in QuarkInfo.SizeX and QuarkInfo.SizeY.
// The RegionSyncPhysEngine has a receive thread to process messages from the RegionSyncServer.
// It is the client side of the synchronization channel, and send to and receive updates from the
// Auth. Scene. The server side thread handling the sync channel is implemented in RegionSyncScriptAPI.cs.
//
// The current implementation is very similar to RegionSyncClient.
// TODO: eventually the same RegionSyncSceneAPI should handle all traffic from different actors, e.g.
// using a pub/sub model.
