/**
10
 * Class definition for the allowed layouts governing structure.
11
 *
12
 * @ingroup mainapi
13
 *
14
 * This class is designed to handle panels allowed layouts data from start to finish, and sees
15
 * action at two times:\n
16
 *    - When a client module wants to generate a form allowing an admin to create or edit a set
17
 *      of allowed layouts. In this case, either a new panels_allowed_layouts object is created
18
 *      or one is retrieved from storage and panels_allowed_layouts::set_allowed() is called to
19
 *      generate the allowed layouts form. \n
20
 *    - When a client module is calling panels_edit_layout(), a saved instantiation of this object
21
 *      can be called up and passed in to the fourth parameter, and only the allowed layouts saved
22
 *      in that object will be displayed on the form. \n
23
 * Because the panels API does not impose a data structure on the allowed_layouts data, client
24
 * modules can create as many of these objects as they want, and organize them around any concept:
25
 * node types, date published, author roles...anything.
26
 *
27
 * To call the settings form, instantiate this class - or, if your client module's needs are
28
 * heavy-duty, extend this class and instantiate your subclass - assign values to any relevant
29
 * desired members, and call panels_allowed_layouts::set_allowed(). See the documentation on
30
 * that method for a sample implementation.
31
 *
32
 * Note that when unserializing saved tokens of this class, you must
33
 * run panels_load_include('common') before unserializing in order to ensure
34
 * that the object is properly loaded.
35
 *
36
 * Client modules extending this class should implement a save() method and use it for
37
 * their custom data storage routine. You'll need to rewrite other class methods if
38
 * you choose to go another route.
