org.das2.qds.BundleDataSet

create a higher rank dataset with dim 1 being a bundle dimension. Each dataset must have the same length. Note this was created before BUNDLE_1 and bundle descriptor datasets were introduced, so this code is suspect. TODO: review and ensure compatibility with updates to bundle dataset semantics. Copied from JoinDataSet in June 2009 Modification History:

• 2012-07-17: allow rank 2 datasets to be bundled. TODO: really? code doesn't look like it!
