A very small and simple "spring-like" ioc implementation.

Well, it's small and simple.
You can use @SimpleBean and @SimpleComponent and @SimpleAutowired for application.
Also, if you're familiar with spring-boot, @SimpleIocBootApplication is also available.

Well, it's too simple!

If you're learning ioc or try to develop a personal application, this might be a little helpful.
Otherwise, use spring instead.
