Add AutoWIG to list of binding generators

[virtuald]

I'm not associated with the AutoWIG project in any way, but I ran across it yesterday and played around with it a bit today. It does what it claims to do -- namely, spit out pybind11 bindings (the default appears to be boost.python). Unfortunately, the documentation is non-existent and to use it effectively it seems you really need to be a conda/scons user, but perhaps this little bump will help others find it and improve it.

I grabbed the text verbatim from their github site.

This looks fine, but the use of first perspective ("[..] our [..]") makes for a strange read in the documentation.

Good point, edited.

@virtuald it's true that the inner documentation is not really good but if you want more details, you can look at the article published (cited in the README) and I forgot to put a link to the following repository https://github.com/StatisKit/FP17 that contains all examples of the article.

Boost.Python is the default since I encountered some problems with my PyBind11 generator (In most cases it works but more work need to be done to references all problems that could be encountered and their solution)

@pfernique I think autowig is very promising, which is why I'd love to see more people trying to use it :)

Merged!
