I want to reduce some complexity around here, part of which is that
launch imported entrypoint imported backend, all to do some proxy
wrapping which isn't necessary for the dev case anyway. Less
layers of wrapping and importing is good. Plus I think this naming
is more clear.
Alright, I got tired of confusing myself with the same-named
outer and inner package.
Keep in mind that every frontend implementation is supposed to be
its own independent project where etiquette is nothing but a
dependency. So the name backend is not ambiguous with the etiquette
backend.
Added a styleguide.md file to refer back to.
Since voussoirkit is a library it feels better to have it below
the rest of the library and above the local project imports.
