/**
 * This abstract class helps you build user relation model.
 * If you want to use group feature, the BaseUserRelationGroup's extended class
 * must be used coordinately.
 * Basic usage:
 * - Implementation:
 * ~~~php
 * class SingleRelation extends BaseUserRelationModel {
 *     public $relationType = 0; // 0 represents single relation, 1 represents mutual relation. 1 is default.
 *     public $multiBlamesAttribute = 'groups'; // you should redeclare this property if needed. 'blames' is default.
 *
 *     public function init()
 *     {
 *         $this->multiBlamesClass = UserRelationGroup::className(); // if you need relation group feature, `$multiBlamesClass` property should be specified.
 *         parent::init(); // parent's call should be placed at the end of init() method.
 *     }
 * }
 * ~~~
 * or:
 * ~~~php
 * class Relation extends BaseUserRelationModel {
 *     public $multiBlamesAttribute = 'groups'; // you should redeclare this property if needed. 'blames' is default.
 *
 *     public function init()
 *     {
 *         $this->multiBlamesClass = UserRelationGroup::className(); // if you need relation group feature, `$multiBlamesClass` property should be specified.
 *         parent::init(); // parent's call should be placed at the end of init() method.
 *     }
 * }
 * ~~~
 * Then you can implememt your own `tableName()` for the name of specified table,
 * and `find()` for convenient of IDE.
 * - Instantiation:
 * ~~~php
 * $relation = $user->findOneOrCreate(SingleRelation, ['other_guid' => $other->guid]);
 * ~~~
 * The above is same as the following:
 * ~~~php
 * $relation = SingleRelation::buildRelation($user, $other);
 * ~~~
