#Spy

Spy is a simple dependency injection container. It gets its flexibility by having dependency injections declared as callables, usually Closures.

##Usage:

$container = new \Spy\Container;
$container->set('http_client', function() {
	return new \Zend\Http\Client;
});

$instanceOfHTTPClient = $container->get('http_client');

You can also pass arguments to your callable in the get call, as such:

$container->set('foo_bar', function($foo, $bar) {
	return new FooBar($foo, $bar);
});

$instanceOfFooBar = $container->get('foo_bar', 'hello', 'world');

You can check if a dependency injection exists by its name with the has method:

print $container->has('yaml_parser'); // bool

You can remove a dependency injection with the remove method:

$container->remove('markdown_parser');
