Priority:
* Data will be labeled in priority order.
- A lower number priority is labeled first.
- Minimum priority is 1.
* Priority is not the queue position.
- The position is determined by the relative priority.
- E.g. [(data_row_1, 5,1), (data_row_2, 2,1), (data_row_3, 10,1)]
will be assigned in the following order: [data_row_2, data_row_1, data_row_3]
* Datarows with parameter overrides will appear before datarows without overrides.
* The priority only effects items in the queue.
- Assigning a priority will not automatically add the item back into the queue.
Number of labels:
* The number of times a data row should be labeled.
- Creates duplicate data rows in a project (one for each number of labels).
* New duplicated data rows will be added to the queue.
- Already labeled duplicates will not be sent back to the queue.
* The queue will never assign the same datarow to a single labeler more than once.
- If the number of labels is greater than the number of labelers working on a project then
the extra items will remain in the queue (this can be fixed by removing the override at any time).
