Workers written in other languages than Python

A Locust master and a Locust worker communicate by exchanging msgpack <http://msgpack.org/>_ messages, which is supported by many languages. So, you can write your User tasks in any languages you like. For convenience, some libraries do the job as a worker runner. They run your User tasks, and report to master regularly.
