	vrpn_Tracker_AnalogFly (const char name, vrpn_Connection trackercon, vrpn_Tracker_AnalogFlyParam *params, float update_rate, bool absolute=vrpn_FALSE, bool reportChanges=VRPN_FALSE, bool worldFrame=VRPN_FALSE)
virtual	~vrpn_Tracker_AnalogFly (void)
virtual void	mainloop ()
	Called once through each main loop iteration to handle updates. Remote object mainloop() should call client_mainloop() and then call d_connection->mainloop(). Server object mainloop() should service the device and then call server_mainloop(), but should not normally call d_connection->mainloop().
