* Provide a debug facility for the queue |

* This debug facility provides a way to easily force some queue behaviors useful for development and testing. |
| 34 |
* To enable this feature, create the file AO_CCSS_DIR . 'queue.json' with a JSON object like the one bellow: |
| 35 |
* |
| 36 |
* {"enable":bool,"htcode":int,"status":0|"str","resultStatus ":0|"str","validationStatus":0|"str"} |
| 37 |
* |
| 38 |
* Where values are: |
| 39 |
* - enable : 0 or 1, enable or disable this debug facility straight from the file |
| 40 |
* - htcode : 0 or any HTTP reponse code (e.g. 2xx, 4xx, 5xx) to force API responses |
| 41 |
* - status : 0 or a valid value for 'status' (see 'Generating critical css - Job Status Types' in spec docs) |
| 42 |
* - resultStatus : 0 or a valid value for 'resultStatus' (see 'Appendix - Result status types' in the spec docs) |
| 43 |
* - validationStatus: 0 or a valid value for 'validationStatus' (see 'Appendix - Validation status types' in the spec docs) |
| 44 |
* |
| 45 |
* When properly set, queue will always finish a job with the declared settings above regardless of the real API responses. |
