   This class extends DtReflectedEntity from VR-Link.

   In VR-Forces, on the Gui side, instances are created instead of instances of DtReflectedEntity.

   Additional note: this class is also responsible for setting up extended DI-Guy decoders, which
   allow the contents of DI-Guy related packets to be controlled from VrfVrlExt, so that modifications
   don't need to be made to code in VR-Link.
