Add test for OrderedDict subclass as NDData.meta
Fix the meta tests
Make Table.meta and NDData.meta behave the same
Use same tests for Table and NDData meta
Update to output (-h,-m,-s) in .hms and .dms, for consistency w/ 0.2
update tests for corrected Angle.hms/dms behavior
Use descriptor for ``meta`` attribute on Table, NDData, Column, and MaskedColumn

Fix for transformations failing if there is a system that can be transformed to but not frow

Make sure that meta is tested on the classes in which it is used
