## org.das2.qstream.filter.QDataSetsFilter

Use this to promote the abstraction of the stream to QDataSets. This was introduced when it became clear that to introduce an FFT filter would be quite difficult with the StreamHandler interface. For example, take a simple rank 2 spectrogram. The DEPEND_1 tags can be encoded inline, or as a single packet. It would be burdensome to have to handle both cases.
