<?php

/**
 * @file alternative to core menu management
 *
 * Needed when menus get to big to load on one page.
 *
 * CONFLICTS WITH tiny_menu. Appropriately enough.
 *
 * Some of the code here - especially the form cache rebuild trigger in
 * bigmenu_slice_form_js() and the parameters sent on the AJAX URL string feel
 * quite ungainly.
 * However the main target - to be able to layer on this flexibility without
 * modifying core - made a few work-arounds neccessary.
 *
 * I did NOT use full Drupal core AHAH routines, as they seemed to rely on the
 * entire form being submitted and rebuilt in the background each page load.
 *
 * As the focus of this module is on *scaling* - I couldn't add that overhead,
 * so the subforms are generated independently, not as part of the main overview
 * form. This is why the bigmenu_slice_form_js() cheats form_cache a little bit.
