Graph validation at compile-time

[benjohnde]

Could be implemented by traversing the Sources and collect each @Inject for creating the dependency-graph. If no circular dependencies are found, continue with collecting information about the dependency container creations and derive the final module catalogue. From here on it is rather easy to validate.

Should potentially work with https://github.com/jpsim/SourceKitten/pull/615/files

SourceKitten still seems to not print out information about annotations. Postponing this one to 1.5.0 (or later).

I am going to tackle that one again, version 0.26.0: Cinco de Gato did not print out information about annotations. Let's see!
