The vendor directory is now just composer stuff. Planning to rearrange some
files soon but wanted to commit these changes. AYAH is now installed via
composer from a package I am maintaining and I dropped the test helpers as it
is a dev-only requirement (and that's assuming you even want to test).
Unsure if that's why I couldn't make the file, thinking of perhaps making the
log directory part of the directory structure instead of creating it on the
fly in Travis CI.
