Unclear docs / examples for unique_args

[untoldone]

There's a lack of docs for what is passed as parameters to the :unique_args lambda / method. What is args? what are the methods on args? In the example, there are three parameters to the method, but what are they supposed to be?

Btw, this was almost certainly less clear due to #193 (comment) as I thought I didn't understand how it works

The args will always be an array of arguments that are passed to the unique_args method. That is just how everything is wired. Even if your job has zero or more arguments the args will be an array.
