Add Apiary

Working on redoing this
our controller specs don't include any links hash for the POST body. 

i thought it was more like this: 
```JSON
{ "classification": 
  { 
    "project_id": 1, 
    "workflow_id": 2, 
    "set_member_subject_id": 1717, 
    "annotations": [
      { "key":  "workflow-1",
        "value": [10.4, 12.4, 13.2]
      },
      { "started_at": "2014-08-24T22:20:21Z" },
      { "finished_at": "2014-08-24T22:24:31Z" },
      { "user_agent": "cURL" }
     ]
  }
}
```
