/// INTRODUCTION
/// This file performs the following tasks:
/// -it defines the necessary objects and interfaces to build the Moodle
/// admin hierarchy
/// -it builds the $ADMIN global object (the admin tree)
/// -it defines the admin_externalpage_setup(), admin_externalpage_print_header(),
/// and admin_externalpage_print_footer() functions used on admin pages
/// ADMIN_SETTING OBJECTS
/// Moodle settings are represented by objects that inherit from the admin_setting
/// class. These objects encapsulate how to read a setting, how to write a new value
/// to a setting, and how to appropriately display the HTML to modify the setting.
/// ADMIN_SETTINGPAGE OBJECTS
/// The admin_setting objects are then grouped into admin_settingpages. The latter
/// appear in the Moodle admin tree block. All interaction with admin_settingpage
/// objects is handled by the admin/settings.php file.
/// ADMIN_EXTERNALPAGE OBJECTS
/// There are some settings in Moodle that are too complex to (efficiently) handle
/// with admin_settingpages. (Consider, for example, user management and displaying
/// lists of users.) In this case, we use the admin_externalpage object. This object
/// places a link to an external PHP file in the admin tree block.
/// If you're using an admin_externalpage object for some settings, you can take
/// advantage of the admin_externalpage_* functions. For example, suppose you wanted
/// to add a foo.php file into admin. First off, you add the following line to
/// admin/settings/first.php (at the end of the file) or to some other file in
/// admin/settings:
/// $ADMIN->add('userinterface', new admin_externalpage('foo', get_string('foo'),
/// $CFG->wwwdir . '/' . '$CFG->admin . '/foo.php', 'some_role_permission'));
/// Next, in foo.php, your file structure would resemble the following:
/// require_once('.../config.php');
/// require_once($CFG->dirroot . '/' . $CFG->admin . '/adminlib.php');
/// admin_externalpage_setup('foo');
/// // functionality like processing form submissions goes here
/// admin_externalpage_print_header();
/// // your HTML goes here
/// admin_externalpage_print_footer();
/// The admin_externalpage_setup() function call ensures the user is logged in,
/// and makes sure that they have the proper role permission to access the page.
/// The admin_externalpage_print_header() function prints the header (it figures
/// out what category and subcategories the page is classified under) and ensures
/// that you're using the admin pagelib (which provides the admin tree block and
/// the admin bookmarks block).
/// The admin_externalpage_print_footer() function properly closes the tables
/// opened up by the admin_externalpage_print_header() function and prints the
/// standard Moodle footer.
/// ADMIN_CATEGORY OBJECTS
/// Above and beyond all this, we have admin_category objects. These objects
/// appear as folders in the admin tree block. They contain admin_settingpage's,
/// admin_externalpage's, and other admin_category's.
/// OTHER NOTES
/// admin_settingpage's, admin_externalpage's, and admin_category's all inherit
/// from part_of_admin_tree (a pseudointerface). This interface insists that
/// a class has a check_access method for access permissions, a locate method
/// used to find a specific node in the $ADMIN tree, and a path method used
/// to determine the path to a specific node in the $ADMIN tree.
/// admin_category's inherit from parentable_part_of_admin_tree. This pseudo-
/// interface ensures that the class implements a recursive add function which
/// accepts a part_of_admin_tree object and searches for the proper place to
/// put it. parentable_part_of_admin_tree implies part_of_admin_tree.
/// Please note that the $this->name field of any part_of_admin_tree must be
/// UNIQUE throughout the ENTIRE admin tree.
/// The $this->name field of an admin_setting object (which is *not* part_of_
/// admin_tree) must be unique on the respective admin_settingpage where it is
/// used.
