jmolecules-archunit : layered architecture with DI

[wangmenghw]

The module covers classical Layered Architecture implementation pattern, in which Interface, Application and Domain layers all depend on Infrastructure layer.

Yet nowadays often Layered Architecture implementations follow Dependency Inversion principle, abstract appropriate interfaces in Application and Domain layer and put concrete technology-specific implementations in Infrastructure layer - this way the Domain layer is at the core (rather than Infrastructure) and that fits more to DDD.

In this setup, the dependency check rules are inversed as well.
