Maven Repository Metadata Model

 This is strictly the model for Maven Repository Metadata, so really just plain objects.

 The metadata file name is:

 * <<<maven-metadata.xml>>> in a remote repository,

 * <<<maven-metadata-\<repo-id>.xml>>> in a local repository, for metadata from a repository with <<<repo-id>>> identifier.
