## org.das2.dataset.ConstantDataSetDescriptor

This class wraps a DataSet to use where DataSetDescriptors are required. This trivially returns the wrapped DataSet regardless of the getDataSet parameters. Originally this class was used with Renderers, which needed a DataSetDescriptor for their operation. Now that they interact only with DataSets, and this class should not be used with them, use Renderer.setDataSet instead.
