Decorating a container

This package provides a Ellipse\Container\OverriddenContainer class which can be used to decorate any Psr-11 container. It takes an associative array of alias => values pairs as second parameter. Once decorated, the container ->has() method will return true when the given alias is a key of this array and the ->get() method will return its associated value. When the alias is not a key of the array, the original container ->has() and ->get() methods are used., _(*5)

It is especially useful when used with ellipse/container-reflection., _(*6)
