A service to generate ids on request, and keep them alive, for distributing across clients -- ideally as process ids used in generating unique ids inside those clients (ala uuid machine id), etc

4 config env vars:

• "PORT" -- default 3000
• "MAX" -- default 65535
• "MIN" -- default 1
• "TIMEOUT" -- default 2000

It's a very straightforward rust project, all the basics get you started with the code:

    cargo run
    cargo test

    curl localhost:3000/next
    curl localhost:3000/heartbeat/1
