/// Generic `Cw721Extensions` which may be extended by other contracts with custom onchain nft and collection extensions.

/// Contract with generic onchain nft and collection extensions allows handling with:
/// - no extensions: by defining all extensions as `Empty` or `Option<Empty>`.
/// - opionated `DefaultOptionalNftExtension` and `DefaultOptionalCollectionExtension`.
///   - `DefaultOptionalNftExtension`: either with nft metadata (`Some<NftExtension>`) or none `None`.
///   - `DefaultOptionalCollectionExtension`: either with collection metadata (`Some<CollectionExtension>`) or none `None`.
/// - custom extensions: by defining custom extensions.
///
/// Generics:
/// - `TNftExtension` for NftInfo extension (onchain metadata).
/// - `TNftExtensionMsg` for NftInfo extension msg for onchain metadata.
/// - `TCollectionExtension` for CollectionInfo extension (onchain attributes).
/// - `TCollectionExtensionMsg` for CollectionInfo extension msg for onchain collection attributes.
/// - `TExtensionMsg` for custom extension msg for custom contract logic.
/// - `TExtensionQueryMsg` for custom query msg for custom contract logic.
/// - `TCustomResponseMsg` for custom response msg for custom contract logic.
///
/// Example:
/// ```rust
/// // instantiate:
/// let contract = Cw721Extensions::<
///     DefaultOptionalNftExtension, // use `Option<Empty>` or `Empty` for no nft metadata
///     DefaultOptionalNftExtensionMsg, // use `Option<Empty>` or `Empty` for no nft metadata
