Inject attribute unusable private method

[longZam]

I'm sorry I'm not good at English.

I want to hide the inject method from the outside. Can you support inject for private methods? The Inject attribute does not work in code like the following:

public partial class Dependent : Node
{
    [Inject]
    private void Constructor(ISomeService service)
    {
        service.Foo();
    }
}

Thanks for creating issue. I have resolved it in #21. Sorry for not accepting your pull request. I made some updates that would have made it incompatible with the current codebase.
