			`class MetaEnum(EnumMeta):`
feat(nodes): address feedback - Address database feedback: - Remove all the extraneous tables. Only an `images` table now: - `image_type` and `image_category` are unrestricted strings. When creating images, the provided values are checked to ensure they are a valid type and category. - Add `updated_at` and `deleted_at` columns. `deleted_at` is currently unused. - Use SQLite's built-in timestamp features to populate these. Add a trigger to update `updated_at` when the row is updated. Currently no way to update a row. - Rename the `id` column in `images` to `image_name` - Rename `ImageCategory.IMAGE` to `ImageCategory.GENERAL` - Move all exceptions outside their base classes to make them more portable. - Add `width` and `height` columns to the database. These store the actual dimensions of the image file, whereas the metadata's `width` and `height` refer to the respective generation parameters and are nullable. - Make `deserialize_image_record` take a `dict` instead of `sqlite3.Row` - Improve comments throughout - Tidy up unused code/files and some minor organisation 2023-05-23 08:59:43 +00:00			`"""Metaclass to support additional features in Enums.`
