## Details
Simple, granular, standards-compliant DI container implementations.

### Features
- Is an implementation of the [PSR-11][] standard.
- Uses some other [standards][dhii/data-container-interface] published separately.
- Includes support for the [delegate lookup][] feature, a.k.a. composite containers, with intuitive override order.
- Easily extensible and adaptable.

### Classes
- [`CachingContainer`][CachingContainer] - A simple container that resolves callable service definitions and caches the
result, guaranteeing the same instance every time. [Cache sold separately][dhii/memoize-memory].
- [`ContainerAwareCachingContainer`][ContainerAwareCachingContainer] - A container that is aware of another container,
perhaps a parent one. Callable definitions will receive the top-most parent container of the chain when resolving. Use
it with [`CompositeContainer`][CompositeContainer] to implement the 
- [`AbstractBaseContainer`][AbstractBaseContainer] - Common functionality for DI containers that store services as internal data.
- [`AbstractBaseCachingContainer`][AbstractBaseCachingContainer] - Common functionality for DI containers that cache resolved services.
