        Creates associations in a repository based on the contents of a source

        specifying a criteria object.

        the types of units being associated. This is done by analyzing the
        unit list and the importer metadata and takes place before the
        destination repository is called.

        Pulp does not actually perform the associations as part of this call.
        The unit list is determined and passed to the destination repository's
        importer. It is the job of the importer to make the associate calls
        back into Pulp where applicable.

        repository's associations into the destination repository.
