/**
 * @file
 * Contains administrative screens for the access control plugins.
 *
 * Access control can be implemented by creating a list of 0 or more access
 * plugins, each with settings. This list can be ANDed together or ORed
 * together. When testing access, each plugin is tested until success
 * or failure can be determined. We use short circuiting techniques to
 * ensure we are as efficient as possible.
 *
 * Access plugins are part of the context system, and as such can require
 * contexts to work. That allows the use of access based upon visibility
 * of an object, or even more esoteric things such as node type, node language
 * etc. Since a lot of access depends on the logged in user, the logged in
 * user should always be provided as a context.
 *
 * In the UI, the user is presented with a table and a 'add access method' select.
 * When added, the user will be presented with the config wizard and, when
 * confirmed, table will be refreshed via AJAX to show the new access method.
 * Each item in the table will have controls to change the settings or remove
 * the item. Changing the settings will invoke the modal for update.
 *
 * Currently the modal is not degradable, but it could be with only a small
 * amount of work.
 *
 * A simple radio
 * control is used to let the user pick the and/or logic.
 *
 * Access control is stored in an array:
 * @code
 *   array(
 *     'plugins' => array(
 *       0 => array(
 *         'name' => 'name of access plugin',
 *         'settings' => array(), // These will be set by the form
 *       ),
 *       // ... as many as needed
 *     ),
 *     'logic' => 'AND', // or 'OR',
 *   ),
 * @endcode
 *
 * To add this widget to your UI, you need to do a little bit of setup.
 *
 * The form will utilize two callbacks, one to get the cached version
 * of the access settings, and one to store the cached version of the
 * access settings. These will be used from AJAX forms, so they will
 * be completely out of the context of this page load and will not have
 * knowledge of anything sent to this form (the 'module' and 'argument'
 * will be preserved through the URL only).
 *
 * The 'module' is used to determine the location of the callback. It
 * does not strictly need to be a module, so that if your module defines
 * multiple systems that use this callback, it can use anything within the
 * module's namespace it likes.
 *
 * When retrieving the cache, the cache may not have already been set up;
 * In order to efficiently use cache space, we want to cache the stored
 * settings *only* when they have changed. Therefore, the get access cache
 * callback should first look for cache, and if it finds nothing, return
 * the original settings.
 *
 * The callbacks:
 * - $module . _ctools_access_get($argument) -- get the 'access' settings
 *   from cache. Must return array($access, $contexts); This callback can
 *   perform access checking to make sure this URL is not being gamed.
 * - $module . _ctools_access_set($argument, $access) -- set the 'access'
 *   settings in cache.
 * - $module . _ctools_access_clear($argument) -- clear the cache.
 *
 * The ctools_object_cache is recommended for this purpose, but you can use
 * any caching mechanism you like. An example:
 *
 * @code{
 *   ctools_include('object-cache');
 *   ctools_object_cache_set("$module:argument", $access);
 * }
 *
 * To utilize this form:
 * @code
 *   ctools_include('context-access-admin');
 *   $form_state = array(
 *     'access' => $access,
 *     'module' => 'module name',
 *     'callback argument' => 'some string',
 *     'contexts' => $contexts, // an array of contexts. Optional if no contexts.
 *     // 'logged-in-user' will be added if not present as the access system
 *     // requires this context.
 *   ),
 *   $output = drupal_build_form('ctools_access_admin_form', $form_state);
 *   if (!empty($form_state['executed'])) {
 *     // save $form_state['access'] however you like.
 *   }
 * @endcode
 *
 * Additionally, you may add 'no buttons' => TRUE if you wish to embed this
 * form into your own, and instead call
 *
 * @code{
 *   $form = ctools_access_admin_form($form, $form_state);
 * }
 *
 * You'll be responsible for adding a submit button.
 *
 * You may use ctools_access($access, $contexts) which will return
 * TRUE if access is passed or FALSE if access is not passed.
