Subject: doc: Initial doxygen framework for NSH SFC project
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A first attempt for a documentation generation using Doxygen for
the NSH SFC project.

Doxygen tagging and documentation in the code still need to be done.

Based on a copy of the Doxygen framework in VPP. Top Makefile added
to (only) build documentation.
