/**
 * TPermissionsManager class.
 *
 * TPermissionsManager handles Permissions authorization and  Roll Based
 * Access Control (RBAC).  Each registered Permission is given a set of
 * {@link \Prado\Security\TAuthorizationRule}s.  The RBAC is based on roles
 * having children roles and permissions, with permissions being thought of
 * as special roles themselves.
 *
 * TPermissionsManager attaches {@link TPermissionsBehavior} to all classes
 * that implement {@link IPermissions}.  This is the main mechanism
 * by which application permissions are registered.
 *
 * The role hierarchy and permission rules are unique to each application.  The
 * permissions configuration is defined in the TPermissionsManager application
 * configuration or in a separate {@link PermissionsFile}. {@link TPermissionsConfigurationBehavior}
 * enables a page configuration to have Permission Configurations as well.
 * A {@link TDbParameterModule} can be specified for loading dynamic roles and
 * permissions.
 *
 * Module XML configurations (and similarly PermissionFile) follows the format, eg:
 * <code>
 * <module id="permissions" class="Prado\Security\Permissions\TPermissionsManager" DefaultRoles="Default" SuperRoles="Administrator">
 *	<role name="Developer" children="all, param_shell_permission, cron" />
 *	<role name="Manager" children="editor, change_user_role_permission, cron_shell" />
 *	<role name="cron_shell" children="cron_add_task, cron_update_task, cron_remove_task" />
 *	<role name="cron" children="cron_shell, cron_manage_log, cron_add_task, cron_update_task, cron_remove_task" />
 *  <role name="Default" children="register_user, blog_read_posts, blog_comment">
 *	<permissionrule name="param_shell_permission" action="deny" users="*" roles="" verb="*" IPs="" />
 *	<permissionrule name="cron_shell" action="allow" users="*" roles="Developer,cron_shell,cron_manage_log" verb="*" IPs="" />
 *	<permissionrule name="register_user" action="allow" users="?" />
 *	<permissionrule name="register_user" action="allow" roles="Manager" />
 *	<permissionrule name="change_profile" action="deny" users="?" priority="0" />
 *	<permissionrule name="blog_update_posts" class="Prado\Security\Permissions\TUserOwnerRule" Priority="5" />
 *	<permissionrule name="cron" action="allow" users="admin, user1, user2" roles="*" verb="*" IPs="*"  />
 *	<permissionrule name="blog_*" action="allow" users="admin, user1, user2" roles="*" verb="*" IPs="*"  />
 *	<permissionrule name="*" action="deny" priority="1000" />
 * </module>
 * </code>
 *
 * and in PHP the same file would follow the following format, eg:
 * 'modules' => [
 * 'permissions' =>[class => 'Prado\Security\Permissions\TPermissionsManager',
 * 		'properties' => ['DefaultRoles' => 'Default', 'SuperRoles' => "Administrator"],
 *		'roles' => [
 *			'Developer' => ['all', 'param_shell_permission', 'cron'],
 *			'Manager' => ['editor', 'change_user_role_permission', 'cron_shell'],
 *			'cron_shell' => ['cron_add_task', 'cron_update_task', 'cron_remove_task'],
 *			'cron' => ['cron_shell', 'cron_manage_log', 'cron_add_task', 'cron_update_task', 'cron_remove_task'],
 *			'Default' => ['register_user', 'blog_read_posts', 'blog_comment'],
 *		],
 * 		'permissionRules' => [
 *			[name => 'param_shell_permission', 'action' => 'deny', 'users' => '*', roles => '*', 'verb' => '*', 'IPs' =>''],
 *			[name => 'cron_shell', 'action' => 'allow', 'users' => 'Developer,cron_shell,cron_manage_log', roles => 'cron_shell', 'verb' => '*', 'IPs' =>''],
 *			[name => 'register_user', 'action' => 'allow', 'users' => '?'],
 *			[name => 'register_user', 'action' => 'allow', 'roles' => 'Manager'],
 *			[name => 'change_profile', 'action' => 'deny', 'users' => '?', 'priority' => '0'],
 *			[name => 'blog_update_posts', 'class' => 'Prado\Security\Permissions\TUserOwnerRule', 'priority' => '5'],
 *			[name => 'cron', 'action' => 'allow', 'users' => 'admin, user1, user2'],
 *			[name => 'blog_*', 'action' => 'allow', 'users' => 'admin, user1, user2'],
 *			[name => '*', 'action' => 'deny', 'priority' => 1000]
 * </module>
 *
 * In this example, "cron" is not a permission, but when used as a permission,
 * all children roles/permissions will receive the rule.  Permissions with children,
 * such as 'cron_shell' (above), will give all its children the rule as
 * well.
 *
 * A special role "All" is automatically created to contain all the permissions.
 * Specifying "all" as a child, is the same as specifying a role as a super role
 * via {@link setSuperRoles}.
 *
 * All users get the roles specified by {@link getDefaultRoles}.  This changes
 * the default Prado behavior for guest users having no roles.
 *
 * Intermediate roles, that are not defined in the user system, may be defined in
 * the hierarchy, in the above example the "cron" role is not defined by the system,
 * but is defined in the role hierarchy.
 *
 * Permission Rules can have multiple rules. they are
 * ordered by natural specified configuration order unless the rule property
 * {@link TAuthorizationRule::setPriority} is set.
 *
 * Permissions authorization rules may use the '*' or 'perm_*' to add the rules to all
 * matching permission names.  Anything before the * is matched as a permission.
 * This does not traverse the hierarchy roles matching the name, just the permissions
 * are matched for the TAuthorizationRule.
 *
 * A permission name  must list itself as a role in TAuthorizationRule for the user to be
 * validated for that permission name for authorization.  This is handled automatically
 * by TPermissionManager with the {@link getAutoAllowWithPermission} property.
 * By default getAutoAllowWithPermission is true, and allows any user with
 * that permission in their hierarchy to allow access to the functionality.
 * This rule priority can be set with {@link getAutoRulePriority},
 * where the default is 5, and -thus- before user defined rules.
 *
 * The second automatic rules includes Modules have their own preset rules that can
 * be automatically added via {@link getAutoPresetRules}.  By default this
 * is true. These rules typically allow owners of the data to be permitted without having
 * a permission-role.  Preset roles can define their own priorities but those
 * without set priorities receive the priority from {@link getAutoRulePriority}.
 *
 * The third, and last, auto-Rule is the final {@link getAutoDenyAll DenyAll}
 * rule. This is the last rule that denies all by default.  The AutoDenyAll
 * gets its rule priority from {@link getAutoDenyAllPriority}.  By default,
 * deny all to all permissions is enabled and thus blocking all permissions.
 *
 * Recursive hierarchy is gracefully handled, in case of any loop structures.
