/**
 * Responsible for dependency injection and creating main NeTEx module
 * objects. This decouple the main classes in the netex module, and serve
 * as a single entry-point to create a {@link NetexModule} witch simplify
 * the code({@link org.opentripplanner.graph_builder.GraphBuilder}) using it.
 * 
 * This class inject the build configuration. This way none of the other
 * classes in the `org.opentripplanner.netex` have dependencies to the
 * {@link BuildConfig}.
 * 
 * The naming convention used is close to the defacto standard used by Spring.
