 * Bug Fixes
   * Fixed issue introduced in 2.3.0 with `AlternatingTable`, `BorderedTable`, and `SimpleTable` that caused
     header alignment settings to be overridden by data alignment settings.

   * `CompletionItems` now saves the original object from which it creates a string.
   * Using `CompletionItems` as argparse choices is fully supported. `cmd2` patched `argparse` to compare input to
     the original value instead of the `CompletionItems` instance.
