+	ZBufferUpdate.hpp
+	Author: James Russell <jcrussell@762studios.com>
+	Created: 9/13/2015
+
+	Purpose: 
+
+	Buffer updates are created by the property buffer when synchronization 
+	happens.  They are then passed along to the network service to be serialized
+	and sent across the wire.
+
+	License:
+
+	TODO
