/****************************************************************************

  P_QUICNetProcessor.h

  The QUIC version of the UnixNetProcessor class.  The majority of the logic
  is in UnixNetProcessor.  The QUICNetProcessor provides the following:

  * QUIC library initialization through the start() method.
  * Allocation of a QUICNetVConnection through the allocate_vc virtual method.

  Possibly another pass through could simplify the allocate_vc logic too, but
  I think I will stop here for now.
