/**
* Generate an aggregate i18n bundle for all dependencies of the project.
*
* The main idea is to have a final unique i18n bundle for an application to
* launch, this really improve i18n loading time to have a unique named bundle,
* no need to seek in all dependencies...
*
* Moreover, this permits also to deal with order of i18n keys, more precisely,
* we want to use the higher level i18n key for an application. If the i18n
* key is present on a library, we want to be able to override it in
* application (or user wants it:)).
*
* This goal permits this using the dependencies graph order of artifacts.
