WebAudio simple single-track sequencer

How to run

1. Create 4 1-bar wav samples with 120 BPM and 44100 Hz named from 1.wav to 4.wav.
2. Run a web server to serve static from the project directory, e.g. python -m http.server and open http://localhost:8000. Just opening index.html in the browser won't work because of CORS policy.
3. Press Play and you should hear your files playing in a sequence.
4. Try stop/resume playing, seeking when playing or idle by moving the Position slider and also changing the Tempo.

Ruby DSL for ULMS interactions with MQTT

The DSL is useful for development, testing and debugging by enabling quickly writing MQTT interaction scenarios.

Advantages over mosquitto:

1. Less boilerplate. Actually while providing all the options to mosquitto I can easily forget what I actually want to do with it. This is damn slow.
2. Ruby is much more nice to read and edit than bash.
