// Description : The Panda interface to a VRPN tracker.  This object
//               will be returned by VrpnClient::make_device(), for
//               attaching to a TrackerNode.
//
//               It represents the data from just one particular
//               sensor of a named VRPN tracker, and may reflect
//               either the sensor's position, its velocity, or its
//               acceleration.
//
//               This class does not need to be exported from the DLL.
