        """
        Creates associations in a repository based on the contents of a source
        repository. Units from the source repository can be filtered by
        specifying a criteria object.

        The destination repository must have an importer that can support
        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.

        If criteria is None, the effect of this call is to copy the source
        repository's associations into the destination repository.
