SimplestPubSub

Arguably pointlessly simple immplementation of local Pub Sub using a registry for dispatch, as per https://hexdocs.pm/elixir/Registry.html#module-using-as-a-pubsub. It doesn't do much but I often end up writing the same code over again, especially in Nerves projects so here it is.

Anticipated questions

This is less code than Left-Pad. Why should I not just implement this directly in my own project?

I'm not stopping you.

Why shouldn't I use Phoenix.PubSub instead?

I'm not stopping you.

This hexicle can be installed by adding simplest_pub_sub to your list of dependencies in mix.exs:
