 one of the following: `{"completed", "failed", "killed", "queued", "working"}`.
 
 * If the status is `queued`, no other information will be available.
 * If the status is `working`, there will be a human readable message contained in "message" that gives further details as to the state of the document.
 * If the status is `complete` there will be a key of "download_url" that will contain a 2 time use URL that, when visited, will provide your document.
 
 There will also be a key of `download_key` that can be given to the `DocRaptor.download` function to obtain your document.  If the status is `killed`, it means the system had to abort your document generation process for an unknown reason, most likely it was taking too long to generate.  If the status is `failed` you can check the `messages` value for a message and the `validation_errors` value for a more detailed reason for the failure to generate your document.
