//
// The demonstartion uses Brannon King's C# wrapper for NLOPT 'C',
// which is available as a NUGET package:
//
//   Github page, NloptNet, C# wrapper around the NLopt C library
//   https://github.com/BrannonKing/NLoptNet
//
//   Another download page for C# Nlopt
//   https://www.nuget.org/packages/NLoptNet
//
//   Notes:
//
//   1) The wrapper syntax IS different than what's given in
//      the NLOPT reference.
//
//   2) The code was translated from C++ which used multiple
//      outstreams, hence the C# coding may be a bit strange.
