Thanks for the suggestion Paul. This ended up being a really good example
to work on.

I was hoping to just grab the precompiled DLL for it but the downloadable
version has a bug in it and would just exit whenever I tried to use it.
With Mark Waddingham's help (a lot of it) I now have a basic version
working on both macOS and Windows. Even the macOS version required some
interesting steps so that the dylibs (pocketsphinx and sphinxbase) would
only load the dylibs in the extension's code folder. Wrapping the code was
also an educational experience and has a number of teaching points that I
will bring up in the workshop.

For those of you who offered up other suggestions - I took a look at the
pages you sent but I didn't see any obvious C interfaces and they also look
like much more involved projects. FFI will not work with C++ right now.
