The SDR classifier updates _patternNZHistory each time compute is called. But clients are calling compute multiple times per record. This is because there are sometimes multiple categories to learn for each record.

We should support this either by allowing multiple categories to be specified to compute or by enabling multiple calls to compute with only a single update to _patternNZHistory.
