     * Gets a paginated collection for the select2 menus
     *
     * This is handled slightly differently as of ~4.7.8-pre, as
     * we have to do some recursive magic to get the hierarchy to display
     * properly when looking at the parent/child relationship in the
     * rich menus.
     *
     * This means we can't use the normal pagination that we use elsewhere
     * in our selectlists, since we have to get the full set before we can
     * determine which location is parent/child/grandchild, etc.
     *
     * This also means that hierarchy display gets a little funky when people
     * use the Select2 search functionality, but there's not much we can do about
     * that right now.
     *
     * As a result, instead of paginating as part of the query, we have to grab
     * the entire data set, and then invoke a paginator manually and pass that
     * through to the SelectListTransformer.
     *
     * Many thanks to @uberbrady for the help getting this working better.
     * Recursion still sucks, but I guess he doesn't have to get in the
     * sea... this time.
