Minimum Element-Set for a Project POM

  In order to furnish a basic set of information which we need to distinguish one
  project from another, maven requires a minimum set of elements to be specified
  in each project's pom.xml.

 During Maven initialization, Maven tweaks default root logging level to match CLI verbosity choice. Since such feature isn't available
 in SLF4J API, logging implementation specific extensions need to be added into Maven to support these CLI options: see
