// A simple class which is responsible for translating Fire PDUs into 
// portal messages and back. 
//
// This is meant as an example. None of the PDUs are translated in any 
// meaningful way. Rather this example is meant to show how to send Interactions
// through the data exchange. Though VR-Link is required to link, only the utility 
// librarys (vlutil, mtl, and matrix) are required. The protocol dependent
// libraries (vl5, vlHLA13 and vlHLA1516) are not required by the data exchange. 
// The protocol libraries are useful for this example for the DIS connection.
