Incomplete documentation.

The README.md to this project suggests that all you have to do is set up Redis, evaluate a Zhong.schedule call, and boom! the job happens as specified. But there is a missing step.

For example, I ran the following in a Rails console running Instacart's own catalog app, which uses Zhong in production. If Zhong "just works" with no configuration whatsoever, evaluating the following should result in a string being printed to the terminal every second:

Zhong.schedule do
  every 1.seconds, 'This should do something' do
    puts 'Hello!'
  end
end

Instead of seeing anything printed to STDOUT, that expression just returns some object and does nothing else.

Zhong does absolutely nothing until the following is evaluated from somewhere:

Zhong.start

There is a bin/zhong script included with this Gem that does almost nothing but this.
