+// LFSGlass.cxx - Network interface program to send data to display processor over LAN
+//
+// Created by: J. Wojnaroski -- castle@mminternet.com
+// Date: 21 Nov 2001
+//
+// Extended from original network code developed by C. Olson
+//
+// Modified 12/02/01 - Update engine structure for multi-engine models
+// - Added data preamble to id msg types
+//
+// Modified 01/23/02 - Converted portions of the Engine and Gear accesssors to properties
+// - Removed data from navigation functions. Glass provides own nav functions
+//
+// Modified 03/05/03 - Modified to reduce need to search property tree for each node per frame
