  - [bug] Removed warning when Index is created
    with no columns; while this might not be what
    the user intended, it is a valid use case
    as an Index could be a placeholder for just an
    index of a certain name.

  - [feature] Added interim create_engine flag
    supports_unicode_binds to PyODBC dialect,
    to force whether or not the dialect
    passes Python unicode literals to PyODBC
    or not.
