## Details
This package contains base implementations of standard [container-related interfaces][dhii/data-container-interface],
which includes exceptions, exception factories, and a small opinionated base implementation that demonstrates
simple common usage. Because the standard is an extension of [PSR-11][], this implementation is compliant with PSR-11.

### Classes
- [`AbstractBaseContainer`][AbstractBaseContainer] - A base class for containers. For the simplest implementation, 
only needs a constructor added.
- [`ContainerException`][ContainerException] - Represents a problem with a container.
- [`NotFoundException`][NotFoundException] - Occurs when a key cannot be found in a container.

### Traits
- [`CreateContainerExceptionCapableTrait`][CreateContainerExceptionCapableTrait] - Creates `ContainerException` instances.
- [`CreateNotFoundExceptionCapableTrait`][CreateNotFoundExceptionCapableTrait] - Creates `NotFoundException` instances
