Detailed Description

This is the actual interface to a particular VRPN tracker object, and all of its sensors.

A pointer to this object is stored in the VrpnClient class for each differently-named VRPN tracker we connect to.

The VRPN callbacks go here, which in turn get vectored out to any VrpnTrackerDevice objects that register with this. When the last VrpnTrackerDevice object unregisters, the VrpnTracker will be deleted by the VrpnClient.

This class does not need to be exported from the DLL.
