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
Use descriptor for ``meta`` attribute on Table, NDData, Column, and MaskedColumn
Removed unused code
Minor fix
Move names processing from Header to Reader ala include/exclude
Move strict names checking from guess() to apply_include_exclude_names
Add tests of reading tables with names arg given
check for stdout.encoding before doing encoding in pytest
add old builtin coordinate systems as vali transform targets
added more transform tricks to make old system names work
Fix for transformations failing if there is a system that can be transformed to but not frow
minor docstring correction
Setting ``meta`` to an empty dict is more explicit than clearing what is currently there.
Make sure that meta is tested on the classes in which it is used
Disable strict names checking when guessing a single reader
use or syntax instead of if statements
