Created virtual sub-classes of DataSet: {Finite{Length,Width},Sliceable}DataSet, removed .field ability from LookupList (because of setattr problems), removed fieldNames() from DataSet (but is in FiniteWidthDataSet, where it makes sense), and added hasFields() instead. Fixed problems in asarray, and tested previous functionality in _test_dataset.py, but not yet new functionality.
