An factory which assigns each aggregate a quality estimate. Originally developed by Napov and Notay in the context of plain aggregation, while this quality estimate does not correspond to a robust convergence guarentee (as it does for plain aggregation), we find empirically that it is a good way of discovering poorly constructed aggregates even in the smoothed aggregation context.

Originally developed by Napov and Notay in the context of plain aggregation, while this quality estimate does not correspond to a robust convergence guarentee (as it does for plain aggregation), we find empirically that it is a good way of discovering poorly constructed aggregates even in the smoothed aggregation context.
