How do we do this?

I'm not totally sure how this works - would ❤️ some brief insight from @springmeyer and @camilleanne!

[springmeyer]

First phase:

• Depend on hpp-skel installed via mason package
• Makefile that handles install of hpp-skel like https://github.com/mapbox/wagyu/blob/lists/Makefile#L11-L23
• Add a main.cpp or cli.cpp that does #include <hello_world.hpp>
• Add a main() function - this is what makes the tool a cli
• Use hpp-skel somehow in that code

Second phase:

• Add basic argument/option parsing (probably depend on boost::program_options)
• Add usage

Example cli tools include:

• https://github.com/mapbox/osm-tiler
• https://github.com/mapbox/timtam
• https://github.com/mapbox/minjur
