the velocities.
08/27/2001 (RD) Added uiuc_initial_init() to help
in starting an A/C at an initial condition
-
+ 02/24/2002 (GD) Added uiuc_network_routine()
+ 03/27/2002 (RD) Changed how forces are calculated when
+ body-axis is used
+ 12/11/2002 (RD) Divided uiuc_network_routine into
+ uiuc_network_recv_routine and
+ uiuc_network_send_routine
+ 03/16/2003 (RD) Added trigger lines in recorder area
