/**
 * A indirection that resolves the instance lazily when {@link #provide()} is invoked. This is
 * mainly used to allow the injection and usage of instances that have a more unstable scope into an
 * instance of a more stable scope.
 * 
 * In contrast to other DI-frameworks this is no core concept. To enable {@linkplain Provider}s
 * install the them through buildin-{@link Bundle}.
 * 
 * But it is also very easy to use another similar provider interface by installing such a bridge
 * {@link Supplier}.
