Dead simple [Automatic Request Repeat]( implementation for independent messages.

Local party sends messages by providing an mfa or a fun/0 to `ARQ.start/2`.

Upon receipt of message, remote party can acknowledge the message (and stop its repeat) by calling `ARQ.stop/1` or sending `:stop` to the requestor process.

## Example:
{:ok, supervisor} = ARQ.start_link()

receiver =
  spawn(fn ->
    receive do
      {sender, msg} ->
        IO.puts "Received #{inspect msg} from #{inspect sender}, telling it to stop."

ARQ.start(fn -> send(receiver, {self(), :hi}) end, supervisor)

## Installation

If [available in Hex](, the package can be installed
by adding `arq` to your list of dependencies in `mix.exs`:

def deps do
    {:arq, "~> 0.3.0"}
