Local entries

You can store value such as object or arbitrary value in air container directly (local entry). Simply invoke $container->set

assert(!$container->has('answer'));
$container->set('answer', 42);
assert($container->has('answer'));
assert($container->get('answer') === 42);

Some other related methods are flush to remove previously set entry, and hasLocalEntry to detect if there's a local entry. (where has take recipe or delegated container into account)
