Hi everyone,

This is my first message on the ML. I've written visualizations in the
Visual Studio Natvis framework for the Boost.Unordered containers and
iterators. This will improve the user experience for anyone using Visual
Studio. The visualizations mirror those of the STL unordered containers as
closely as possible, except that end iterators display as "{ end iterator
}" instead of the visualization just breaking.

Here is the file:
https://github.com/boostorg/unordered/blob/develop/extra/boost_unordered.natvis

I've written an accompanying article about the natvis implementation for
the closed-addressing containers. I will be writing a second article about
the implementation for the open-addressing containers. This first article
contains some tips and tricks for using the natvis framework that I wish I
knew before going into this, especially about using "<Intrinsic>" elements.
Hopefully it can help someone else.

Custom gdb pretty-printers will be next up.

Thank you to Joaquín for reviewing the code and the article.

Thanks all,
Braden Ganetsky
