Detect circular dependency and panic

Which one do you prefer to be implenmented first: runtime check or static check? If later, I think we may need a extra tool because there is less support for compiling code in Golang.

I would prioritize a runtime check, since the services can be invoked/replaced in a dynamic way.

And as you said, we won't need an extra tool.

This dependency graph should come with debug functions, in order to understand how the application is booted !

LGTM, I will do a detector in runtime.

Will be added into v2 -> #45
