Full remote build usable example

[treeder]

A follow up to #79 is to get this example: https://github.com/iron-io/iron_worker_examples/tree/master/ruby_ng/image_processing

working like this:

• iron_worker upload https://github.com/iron-io/iron_worker_examples/blob/master/ruby_ng/image_processing/image_processor.worker
• iron_worker queue image_processor -p "{"image_url": ......., all the aws configs, etc from the config_example.yml .... }"

Extra points (optional):

• Pass in which image operations should be performed and the values required to perform them, for eg:

  [ "generate_thumb": {"width": 200, "height": 200, "format": "jpg"}, "operation2":....]
