/**
 * Organization.
 * This class is used to describe an organization or department, depending on the type property.
 * Organization or department should be created by the user, it is best not to directly implement their own such.
 *
 * In general, the organization needs to have `setUpOrganization` permission, and the user does not have this permission
 * by default. You need to give this permission to the user who created the organization in advance.
 * Department, affiliated with the organization or other department, also need the appropriate permission to set up.
 *
 * While this can work independently, we still strongly recommend that you declare the Organization class yourself and
 * inherit this.
 * Then you need to specify the Profile and Member class yourself, like following:
```php
class Organization extends \rhosocial\organization\Organization
{
    public $profileClass = Profile::class;
    public $memberClass = Member::class;
}
```
 * If you need to limit the number of subordinates, the number of members, you need to specify the appropriate class
 * name.
 * If there is no limit, you need to set it to false manually.
 *
 * @method Member createMember(array $config) Create member who is subordinate to this.
 * @property int $type Whether indicate this instance is an organization or a department.
 *
 * @property bool $isExcludeOtherMembers Determine whether the other organization and its subordinate departments
 * members could join in the current organization and its subordinate departments. (Only fit for Organization)
 * @property bool $isDisallowMemberJoinOther Determine whether the current organization and its subordinate
 * departments members could join in the other organization and its subordinate departments. (Only fit for Organization)
 * @property bool $isOnlyAcceptCurrentOrgMember Determine whether the current department only accept the member of
 * the top level organization. (Only fit for Department)
 * @property bool $isOnlyAcceptSuperiorOrgMember Determine whether the current department only accept the member of
 * the superior organization or department. (Only fit for Department)
 * @property string $joinPassword
 * @property string $joinIpAddress
 * @property string $joinEntranceUrl
 * @property bool $exitAllowWithdrawActively
 *
 * @property-read Member[] $members Get all member models of this organization/department.
 * @property-read User[] $memberUsers Get all members of this organization/department.
 * @property-read User $creator Get creator of this organization/department.
 * @property-read User[] $administrators Get administrators of this organization/department.
 * @property-read SubordinateLimit subordinateLimit
 * @property-read MemberLimit memberLimit
 * @property-read static|null $topOrganization The top level organization of current organization or departments.
 * @property-read Profile $profile Get profile model. Friendly to IDE.
 * @property-read OrganizationSetting[] $settings Get all settings.
